Installing Composer

1:37 with Alena Holligan

Before Composer can do anything for you, it needs to be installed. Learn some tips for installation and further instructions in the notes.

Tips

  1. Install globally
  2. Match your development environment
  3. Do NOT include your vendor folder in your Version Control System (VCS)

Installation - Linux / Unix / OSX

For additional help, see the Documentation

php composer-setup.php --install-dir=bin --filename=composer
mv composer.phar /usr/local/bin/composer

Note: If the above fails due to permissions, you may need to run it again with sudo: sudo mv composer.phar /usr/local/bin/composer

Installation - Windows

For additional help, see the Documentation

Download and run Composer-Setup.exe. It will install the latest Composer version and set up your PATH so that you can just call composer from any directory in your command line.

    Before Composer can do anything for you, it needs to be installed. 0:00
    If you're using work spaces, we've got you covered. 0:04
    But if not, check the notes associated with this video for 0:07
    detailed install instructions based on your operating system. 0:10
    Either way, there are three things to keep in mind when installing and 0:14
    using Composer. 0:18
    First of all, Composer can be installed in two ways. 0:20
    Either on a per project basis, so 0:24
    that you can only access Composer from your project directory. 0:26
    Or globally, so that you can access Composer from any project, 0:30
    regardless of the location on your machine. 0:34
    I recommend using the global install, so 0:37
    you don't have to worry about this step for any other projects. 0:39
    Second, you want to install a version of Composer that matches your development 0:44
    environment, not your application's runtime environment. 0:48
    So if you're coding on a Mac, be sure to install Composer for 0:52
    Mac, regardless of whether your app runs on a map server or 0:55
    even on a virtual machine running Linux or Windows. 1:00
    You’ll access Composer commands from a terminal or 1:04
    command line in the actual machine on which you're working. 1:08
    Which brings us to the third and final point to keep in mind when using Composer, 1:12
    avoid committing downloaded packages to a version control system or VCS such as get. 1:17
    Each developer will use Composer to download those packages themselves. 1:25
    This helps keep your repositories tidy and 1:29
    easier to maintain by not cluttering them with all the dependencies. 1:32
