How to install symfony with composer?

Question

I am using Windows 10 When I install symfony2 with:

composer create-project symfony/framework-standard-edition my_project_name

Error:

bash: composer: command not found

To downloads symfony, you need to download symfony.phar (a small file PHP) from this link.

• Then, you have to move in your usual Web directory C:\wamp\www on windows and /var/www on Linux ;

• Execute php symfony.phar new project_name_and_version for example : symfony.phar new symfony2.8 to download Symfony 2.8.

  Then, you can :

• Change your current directory to /var/www/html/project_name on Linux or C:\wamp\www on windows;

• Configure your application in app/config/parameters.yml file ;

• And (always) read the documentation at http://symfony.com/doc.

Good luck ^^ !

Update:

In Symfony 4 the symfony installer is abandoned. So, to create a new Symfony application you need:

• to have PHP 7.1 (or higher)
• to run php composer.phar create-project symfony/skeleton my-project "3.4.*" in your terminal.

You need to install composer before. From your command line:

php -r "readfile('https://getcomposer.org/installer');" > composer-setup.php
php -r "if (hash('SHA384', file_get_contents('composer-setup.php')) === '7228c001f88bee97506740ef0888240bd8a760b046ee16db8f4095c0d8d525f2367663f22a46b48d072c816e7fe19959') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

The recommanded way to install Symfony is through a command, named symfony.

Read the docs from the official symfony website: http://symfony.com/doc/current/book/installation.html, for more info.

So,

• If you are using MAC/Linux: http://symfony.com/doc/current/book/installation.html#linux-and-mac-os-x-systems

• $ cd /var/www/

• $ symfony new my_project_name (more readable example: $ symfony new Blog). This will create a directory (named Blog) inside your /var/www/ directory, where all the code will be housed.

Then you can install composer, as the official docs says, and use it for installing packages inside your Symfony project.

Happy coding!

I tried this one:

php symfony.phar new symfony2.8

The results is this

[RuntimeException]
The Symfony Installer is not compatible with Symfony 4.x or newer versions.
Run this other command to install Symfony using Composer instead:
composer create-project symfony/skeleton symfony2.8

I tried the suggested command and it start download and install automatically

composer create-project symfony/skeleton symfony2.8

When i tried php -r "readfile('getcomposer.org/installer');" > composer-setup.php Error: bash: composer-setup.php: Permission denied

Because you run this command in place when you don't have proper privileges. Please do it in /home/user_name or use 'sudo' before used command.

Try the command from your project's root directory (the one containing the app, vendor, src and web directories).

To install a version 3 symfony, you can persevere with your original command by putting the version on the end - "symfony new my_first_app 3.4"
