Installing Drush on WSL

Question

How should I install Drush on WSL when running the following command shown in the Drush documentation fails?

php -r "readfile('http://files.drush.org/drush.phar');" > drush

Answer 1

Better to follow this to require with composer: https://www.drupal.org/node/1248790

1. Install composer globaly:

   $ curl -sS https://getcomposer.org/installer | php

   $ sudo mv composer.phar /usr/local/bin/composer

2. Require drush:

   composer global require drush/drush:7.*

The instructions in drupal.org also show how to add the path so you can use drush from everywhere.

Im working with WSL and it works great.
