Lately I was trying to install drush for the first time. This is what I did..

  • Installed the drush tool manually
  • Extracted and renamed the tool to /Library/Drush
  • Gave the /Library/Drush/drush tool execution permissions.
  • Created an alias for drush in ~/.bashrc
  • Tried to bash drush by entering the alias drush, that's when I got the first problem: Unable to load autoload.php. Drush now requires Composer in order to install its dependencies and autoload classes. Please see README.md
  • After lots of searching I tried way to many things:
    • which drush doesn't return anything.
    • Installing the composer (at /usr/local/bin/composer) results in this The requested package drush/drush 1.0.0 could not be found problem when executing composer global require drush/drush:dev-master

Help would be appreciated, because I don't know what I could do to make it work.

Thank you in advance, `F.

    If you're struggling to do it manually, why not just use Homebrew? brew install drush is all you need

I have encountered the same error while installing the drush on MAC, I have tried the following and that worked for me:

composer self-update
ln -s /path/to/drush/drush /usr/bin/drush

I have downloaded the Drush from this git repository: https://github.com/drush-ops/drush

And followed the method described here for installing the Drush on MAC: https://www.drupal.org/node/1674222

For Installing Drush on Mac using Homebrew, check https://www.drupal.org/node/954766

  • This didn't work for me neither, still got the same error. But I didn't used the drush download you use (drush-master). The additional solution @Clive commented did work!

  • @Fleuv Yes for MAC using Homebrew is a good option, anyways I have also mentioned this as well as a alternate option :) Commented Sep 16, 2014 at 15:46
