Login SubscribeThanks to the Flex recipe for symfony/framework-bundle, we now have a fully-functional Symfony Flex app living right inside our directory! public. is the new document root, config/ has all of the configuration, and our PHP code lives in src/, including the new Kernel class.
Yep, we have our old app with all our stuff, and a new, Flex, app, which is basically empty and waiting for us to move our code into it.
Open up .env.dist. Woh! This has more stuff now! That's thanks to the recipes from DoctrineBundle, SwiftmailerBundle and FrameworkBundle. Copy the FrameworkBundle section and move that to the top. Do the same thing to .env.

We don't need to do this, but APP_ENV is so important, I want to see it first. If you start a new Flex app, it's on top.
Next, this will sound weird, but run:
composer require symfony/flex
We already have this library. I know. So... why are we doing this? It's a little trick: one of the new keys in our composer.json is sort-packages, which is set to true. Thanks to this, whenever you run composer require, it orders the packages alphabetically. By requiring a package we already have, Composer just re-ordered my packages.
Thanks Jordi!
But... we still have this giant error: attempted to load SecurityBundle from AppKernel. Bummer! This happens because bin/console is still trying to boot the old app.
When you start a new Flex project, the symfony/console recipe creates the bin/console file. But, since our project already had this file, the recipe couldn't do its job.
No worries! Let's go find the new file! Go to github.com/symfony/recipes. Welcome to the official recipes repository!
Navigate to symfony, console, then bin. There it is! Copy its contents. Then, completely replace our version.
| #!/usr/bin/env php | |
| use App\Kernel; | |
| use Symfony\Bundle\FrameworkBundle\Console\Application; | |
| use Symfony\Component\Console\Input\ArgvInput; | |
| use Symfony\Component\Debug\Debug; | |

| set_time_limit(0); | |
| require __DIR__.'/../vendor/autoload.php'; | |
| if (!class_exists(Application::class)) { | |
| throw new \RuntimeException('You need to add "symfony/framework-bundle" as a Composer dependency.'); | |
| } | |
| ... lines 17 - 40 |
This will boot the new application! So... does it work? Run:
./bin/console
No! But that's a new error: we are closer! This says that the autoloader expects App\AppBundle\AppBundle to be defined in AppBundle.php, but it wasn't found. That's strange... that is not the correct namespace for that class! If you look closer, it says the error is coming from a new config/services.yaml file.
Our old code - the stuff in src/AppBundle - should not be used at all by the new app yet. Open that new config/services.yaml file. It has the same auto-registration code that we're familiar with. And, ah ha! Here's the problem: it is auto-registering everything in src/ as a service, but it's telling Symfony that the namespace of each class will start with App\. But, our stuff starts with AppBundle!
For now, completely ignore AppBundle: let's get the new project working and then migrate our code.

Ok, try bin/console again:
bin/console
It's alive! We just hacked a fully-functional Flex app into our project! Now let's move our code!
I had the same error, there was some reference to that VarDumper class that needed to be removed... But I don't remember where exactly anymore
Hmm, an error like this just should not happen. I mean, Composer has basically set itself up to know that a specific file exists, but then it fails because that file is not there :). I believe this is just a side effect of the upgrade process, and to fix it, you should:
rm -rf vendor/*
composer install
If you look at the error closely, it looks for the dump.php function inside vendor/symfony/symfony/... But during the Flex upgrade process, we stop including the symfony/symfony package, and start including the specific packages we need. This means that the real path to this by the end of the tutorial would be something like vendor/symfony/var-dumper/... - and that's why I think it's just some weird Composer error as we massively change the vendor/ directory.
Let me know if that helps!
I was removing vendor, I was removing cache and then do composer install many times. Error didnt disappear.
For now I just did git reset --hard started from the begining. Maybe this time...
No comments.... I was checking that file so many times and missed that somehow :/ Thanks the_nuts :)
It's the same problem ...
I think this vidéo is ... old ... and the flex recipes are update since this video time ...
Hey Vince,
Yes, some changes were done to the Symfony Flex logic - things are evolving very quickly :)
Cheers!
Hi, it's possible to have issue for this type of erros ?

Hey Vince,
It's more complex :) First of all, that include_path you see in the error message is something specific to Windows, PHP is looking into some standard paths and seems that path is one of them... but you. don't have to have it, so nevermind!
About the actual error - did you run the composer install? Please, try to run composer install again just in case. Also, do you have symfony/var-dumper package installed? If not, or if you just not sure, please, run: composer require symfony/var-dumper to install it.
And if you still see the same error - most probably you're trying to load the website in a different from dev Symfony mode? What env are you trying to load the app?
Cheers!
Thank you, after a long time to change, reinstall things, I've resolve this issue ( I don't remember how .. sorry )
I update a very old project with a lot of bundles hand maked, it's hard to fix everythings issues one by one..
It's weird, It's like flex does the half job.
Step by step it's the best..
cheers to ;)
I have followed along each step but where you get a console working, I only get

Hey Mattias,
I'm afraid your Symfony version is not compatible with the new way of handling environment-specific confirguration. You'll need to upgrade Symfony first or you could just keep using the old way
Cheers!
I'm confused... The whole point of this screencast is to guide me through upgrading to 4.0
I have followed the steps as outlined, and all vendors successfully installed including symfony 4.
What do you mean by my version is too old?
Yes, this tutorial guides you through upgrading from Symfony 3 to 4 but you're trying to use a feature of Symfony 5.3+ which is the when keyword in config files. I don't see we use that feature in this tutorial. Could you tell me where you did you get the config code of your config/packages/monolog.yaml file?
I'm only trying to get to version 4.0 😂 perhaps I accidentally got a much too new version? I did not put that config file there manually, it must have been generated by composer.
Here's my composer.json:
"require": {
"php": "^7.1.3",
"doctrine/doctrine-bundle": "^1.6",
"doctrine/doctrine-cache-bundle": "^1.2",
"doctrine/orm": "^2.5",
"friendsofsymfony/user-bundle": "~2.1",
"sensio/framework-extra-bundle": "^5.0.0",
"symfony/console": "^4.0",
"symfony/flex": "^1.19",
"symfony/framework-bundle": "^4.0",
"symfony/lts": "^4@dev",
"symfony/monolog-bundle": "^3.1.0",
"symfony/polyfill-apcu": "^1.0",
"symfony/swiftmailer-bundle": "^3.1",
"symfony/yaml": "^4.0",
"twig/twig": "^1.0||^2.0"
},
"require-dev": {
"symfony/dotenv": "^4.0",
"symfony/phpunit-bridge": "^4.0"
},
It should all be according to the tutorial. Do I need to restrict any of these to a lower version?
It seems like removing the monologe.yaml all together solved the problem for now. But still curious how I ended up with it, it was autogenerated for sure. Could it be that composer first installed 5.4 (and ran recipes for that?) and only later in the process downgraded it to 4.4? I didn't follow the composer log maticulously upon install there.
Hey, sorry for my late reply, the weekend got in the middle :)
I think you're right, Symfony Flex installed a higher recipe version of monolog for some reason. I'm not sure why but perhaps monolog bundle v3.7 supports Symfony 4.4. Double-check what version of monolog you got install
Cheers!
Thank you. I've downgraded in composer.json to "symfony/monolog-bundle": "3.4.*", and then run composer recipes:update
solved the issue.
Hi,
I got error
PHP Fatal error: Uncaught Symfony\Component\Debug\Exception\FatalThrowableError: Xdebug has detected a possible infinite loop, and aborted your script with a stack depth of '256' frames in /home/user/projects/myproject/vendor/doctrine/persistence/lib/Doctrine/Persistence/Mapping/Driver/SymfonyFileLocator.php:84
any idea?
Hey Hendra,
Looks like you have an infinite loop somewhere in the code. Please, double check it. I think you can look at error stacktrace on the Symfony error page to get more info about the calls - this should help to figure out the problem spot. It's good that you have Xdebug installed, otherwise the page will just hang for you in infinite loop, but in your case you have just an error. So, try to debug it further to find the root of the problem
I hope this helps!
Cheers!
How do we handle @template in the old appbundle controllers? I get errors of: Unable to find template (Lookeed into: project/templates). In this tutorial I dont think we told symfony to look for the twig templates in the old app bundles. Would it require removing all the @template annotations and changing to rendering the full path to the template instead for all the app bundle controllers? If that is the case probably just better off to finish moving to the flex structure.
Hey Michael L.!
Hmm, that's a good question - I'm not directly familiar because I don't use @Template. But yes, as soon as AppBundle is gone... then it would start looking for controllers in project/templates. My first instinct is the same as your's: finish moving those templates to their new location - that might be the easiest path. This upgrade can be painful - keep it up! It won't be repeated again - the upgrade from 4 to 5 is super easy.
Cheers!
Hello !
At 2'2 you explain to go to https://github.com/symfony/... and copy the console/bin content.
When I go to that URL, I have two folders : 3.3 and 4.4. Which one should I pick since I use Symfony 4.3.5 ?
By the way, huge thanks for the subtitles. As a deaf 🧏🏻♂️ developer, It helps me a lot !
Keep up the amazing work !
Hey Levure
I'm so glad to hear that subtitles are really useful to you :) (I'm who implemented it)
About your question. I think you can just use the code from 4.4, give it a try and if it doesn't work let me know
Cheers!
Hi, I followed the tutorial, but public/index.php , src/Kernel.php , config/services.yaml ... are missing. any idea why ?
Hey Daniel L.!
Hmm. The recipe from symfony/framework-bundle should have given you these files. It makes me think that recipe didn't run. First thing to try: empty your vendor directory and run "composer install" - that might trigger that recipe to execute, if it didn't for some reason.
Cheers!

Hey Disha
Is probably that the namespace of such class it's wrong. Could you double check it?
Oh, and what's inside "MyApp" folder? because I see you also have "AppBundle"
Cheers!
It was working correctly with symfony 3.4, do we have to change namespace for all the classes for 4.1 upgrade?
MyApp is a folder in which all my application bundles are. like src/MyApp/LocationBundle, src/MyApp/MediamanagerBundle, src/MyApp/EventBundle ect. AppBundle is at src/AppBundle.
Inside : AccessPointDataAdmin.php
namespace MyApp\AccessPointDataBundle\Admin;
please help.
If you don't want to migrate all your bundles then you will have to exclude them from being auto-registered as you did to the AppBundle:
exclude: '../src/{DependencyInjection,Entity,Migrations,Tests, *AppBundle*, Kernel.php}'
If you have more bundles than the demo app you might get errors likes :
The child node "db_driver" at path "fos_user" must be configured.
I suppose, this is because the bundle don't provide a config file, so at the moment to stick with the course I just commented those bundle in config/bundles.php
Hey Kaizoku ,
You're right, because the recipe is not yet available. Some bundles still have no release tag for Symfony 4 support like FOSUserBundle. If you use this bundle, you can point to dev-master in composer.json for it and also check the original PR: https://github.com/FriendsO... - you'll find some temporary workarounds.
Cheers!
I think I messed up things with git checkouts between 3.4 and 4.0... For example the src/Controller directory is missing... how can I reconfigure flex?
Hey Trafficmanagertech ,
What do you mean about reconfiguring Flex? Did you require Flex with Composer as we show in this chapter? You can manually create src/Controller directory and move there all your controllers from the old src/AppBundle/Controller.
Cheers!
Yes, at the end I started over... Anyway I have another error, "ClassNotFoundException: Attempted to load class "SensioDistributionBundle" from namespace "Sensio\Bundle\DistributionBundle"".
Do I need to remove the Sensio lines from the AppKernel.php?
Hey Trafficmanagertech ,
Hm, that's the correct namespace, see: https://github.com/sensiola... . Please, make sure you have installed "sensio/distribution-bundle", I think you can check it with Composer:
composer info sensio/distribution-bundle
If it's not installed, then you need to comment it out in AppKernel or remove this line from there at all.
Cheers!
...after removing it from bundles.php (I see it's not present in his finished project folder) it worked. sorry for so many questions :))
Hey Trafficmanagertech
Looks like something else is trying to require that class and by looking at your screenshot I can see it comes from a cached class; try removing entirely your var/cache/dev folder
$ rm var/cache/dev/*```
Cheers!
It didn't work, I fixed it with a `composer require sec-checker`, but honestly I don't know why it was needed, I never used that library...
Hey Trafficmanagertech ,
Hm, probably you have a dependency which requires sec-checker, but in this case "composer update" had to download it for you, so difficult to say something more without deeper debugging.
Anyway, glad you fixed and this error ;)
Cheers!
OK, so if you deleted it - then yes, remove it from AppKernel too otherwise it will cause errors ;)
Cheers!
