    Hey Rachel!

    No worries :) - you have 2 options:

    1) The second code block on the download page - https://getcomposer.org/dow... - shows an option that *doesn't* use curl. This may work for you!

    2) Since composer is just a single file (composer.phar), you can just upload this to your web server. You could even commit it to your version control repository - It's generally not considered a best practice, but it's no big deal.

    Good luck!

    Confused noob here. I installed composer on my local machine but I cannot figure out how to install it on my web server. I do not have curl. Can anyone help? I'm trying to use a MailChimp plugin that requires composer

    Hey Edison!

    Oh man, *great* question! I realize that I didn't put very good comments on that file in the script :). I've just made some changes to show you were this is (https://github.com/knpunive... - you should already see these deployed! Basically, I'm putting things into a custom module called `list_files` that I already created and enabled before the tutorial.

    I hope that helps! And good luck with the tutorials - ping me if you need anything!

    Cheers!
