I just started to learn Symfony framework and I got stuck on very begging.
I created with composer with following commands:
composer require symfony/maker-bundle --dev
composer require annotations
php bin/console make:controller ToDoListController.php
Code looks good, but when I try to open this controller I am getting an error message:
Uncaught Error: Class 'Symfony\Bundle\FrameworkBundle\Controller\AbstractController' not found in C:\xampp\htdocs\symfony44\src\Controller\ToDoListController.php:9 Stack trace: #0 {main} thrown in C:\xampp\htdocs\symfony44\src\Controller\ToDoListController.php on line 9.
I am using xampp as a local server, symfony 4.4
Has anyone encountered with this problem?
Please install symfony using the symfony app. Download the app for windows from https://symfony.com/download.
Open the windows command prompt.
type the following commands
symfony new project-name --full
cd project-name
symfony serve
symfony serve starts your development server. Use apache when your app is deployed. With the symfony app you can use https. This method of symfony installation is easy and it is good for those new to symfony. With the --full option maker bundle and all other important bundles are installed for you. You can just start creating controllers
Everywhere I look in the Symfony documentation for Symfony 4.2, it says that to clear the cache, I run:
php bin/console cache:clear
However, this bin/console is a relative path. I can't find bin/console anywhere. I've done a find on my composer vendor directory. Nothing.
Where is bin/console?
I'm running php 7.2.
Symfony 4.x structures in like this (From CoderSkills)
If you don't have the same after your installation, remove your project folder and create a new ones by running composer create-project symfony/website-skeleton myNewProject
Here is a guide to start a new Symfony project
I have tried to install the Symfony 4 on my Macbook Air by using Composer. I have used the below commands for installing and running Symfony application
composer create-project symfony/website-skeleton symfony4
cd symfony4
composer require server --dev
php bin/console server:run
And then tried to access the application in http://127.0.0.1:8000/. Below is the error message
Below image shows the error in which line and file
I am using PHP 7.2.3 and installed by using Homebrew. At the same time when I use the below command to install, Symfony welcome page appears without any error.
composer create-project symfony/skeleton symfony4
There is no default welcome page when you create new symfony flex application and there is an issue and a pull request already.
Everything is working fine you just don't have any pages.
Here you can read how to create a symfony page: https://symfony.com/doc/current/page_creation.html
When I run the server using php bin/console server:run I get the following error.
There are no commands defined in the "server" namespace.
When I run php bin/console command I egt the following output. Which does't show any server: commands.

Is there anything else that I can try?

As I mentioned in my comment, in S3.3 the server commands have been moved to their own WebServerBundle. Some editing of AppKernel.php is required to activate the bundle. I suspect that many other developers might run into this once 3.3 is actually released and people try upgrading.
I make no promises but try updating AppKernel.php with:
if (in_array($this->getEnvironment(), ['dev', 'test'], true)) {
$bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
$bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
$bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
if ('dev' === $this->getEnvironment()) {
$bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
$bundles[] = new Symfony\Bundle\WebServerBundle\WebServerBundle();
}
}
I don't have a good test project to try it on but at least the commands should show up.
And in case anyone is wondering, all I did was to install a fresh development project and poked around a bit.
composer create-project symfony/framework-standard-edition s33 "3.3.*" --stability=dev
I also found this but it does not mention the need to update AppKernel.php
http://symfony.com/blog/new-in-symfony-3-3-webserverbundle
From the upgrade guide: https://github.com/symfony/symfony/blob/3.4/UPGRADE-3.3.md
The server:run, server:start, server:stop and server:status console commands have been moved to a dedicated bundle. Require symfony/web-server-bundle in your composer.json and register Symfony\Bundle\WebServerBundle\WebServerBundle in your AppKernel to use them.
As long as your composer.json has symfony/symfony in it then there is no need to add the web server bundle to it. Just need to adjust the AppKernel file.
run this command before starting the server.
composer require symfony/web-server-bundle --dev
you must execute this command:
composer req webserver
Type:
php bin/console
You'll see all the commands allowed.
If you want to use the server commands you should install it typing on your project:
composer require server --dev
run again
php bin/console
and you should be able to see it and use it.
As #Barh says, you must have APP_ENV=dev in your .env file.
Otherwise Symfony 4 will not be runnable in dev mode.
Verify that the correct APP_ENV is set in the environment.
In my case, it was critical.
you can put this:
php -S localhost: 8000 -t public
or if you are working on symfony 4.x try this command line in your browser:
symfony server: start
don't forget to install symfony CLI before this start from this:
https://symfony.com/download
Since symfony 4.2 and newer, theres is some changes so, to works you have to do this :
1: composer require symfony/web-server-bundle --dev
2: php bin\console --env=dev server:run
upgrading from symfony <3.3 to symfony >3.3 will cause this problem because the web server was extracted out to a separate bundle.
so you'll need to require this bundle:
composer require symfony/web-server-bundle --dev
and in your AppKernel
if ('dev' === $this->getEnvironment()) {
$bundles[] = new Symfony\Bundle\WebServerBundle\WebServerBundle();
}
for more info: check here
I had same issue on Symfony 4 after switching in .env to prod. Some commands are not visible on prod.
You either need to swap to dev or:
bin/console --env=dev
And so to start server:
bin/console --env=dev server:run 0.0.0.0:8005
For symfony 4 and more you should type php -S 127.0.0.1:8000 -t public to start the server
Disabling firewall help
running......composer clear cache helped in allowing permission
running......composer req webserver helped clear my commands defined in the "server" namespace
Remove env.local file if you've it.
Reson:
Because server:run is not executing on production environment
I'm new on symfony, after following instruction to install it, it said i have to run:
bin/console server:run
i type it on my symfony instalation folder. but i got error:
Could not open input file: bin/console
and then i'm searching the answer in here and it told me to run app/console
bin/console server:run
but it just got the same problem. is it i miss some bin folder here or something? since i can't see bin folder or app folder on my project root folder. here's my project folder structure:
You obviously cloned a Git repo, which does not contain all Symfony framework components.
You have to create symfony project through
symfony installer http://symfony.com/doc/current/setup.html
or
with composer composer create-project symfony/framework-standard-edition my_project_name.
