I've been trying to install github-pages using gem. I have Ruby v. 2.1.2:
✦ ruby -v ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux]
I installed Ruby using RVM and I've set 2.1.2 as my default version to use. Somehow, I'm still getting this error message:
✦ sudo gem install github-pages ERROR: Error installing github-pages: jekyll requires Ruby version >= 2.0.0.
