how to install composer globally on macOS

Downloading directly from the composer website

Copy and paste that link – – to your browser. It’s always the latest version of Composer.

After getting it, open your terminal to test it. You need just run that command:

php ~/Downloads/composer.phar --version

I assume that you don’t want to write … every time when you need to use a composer. Let’s move it to bin directory.

You can’t perform that action at this time.
