Hi, my first post to this ml. I am trying to install Rails on a Fedora 20 machine. I think I did, and I see the welcome page at localhost:3000. However, I have a couple of issues: 1- Anytime I insert a line command, I get the following: Invalid gemspec in [/usr/share/gems/specifications/sqlite3-1.3.7.gemspec]: undefined local variable or method `s' for Gem::Specification:Class I am not sure how to fix it. 2- I just realized that I have folders /usr/local/share/gems /usr/local/share/ruby (not rubygems) and /usr/share/gems /usr/share/ruby /usr/share/rubygems 3. I have /usr/share/gems/gems/sqlite3-1.3.7 /usr/local/share/gems/gems/sqlite3-1.3.9 [root@localhost ~]# gem list | grep squ* sqlite3 (1.3.9) 4. If I try to gem clean, i get: [root@localhost new_app]# gem clean Invalid gemspec in Cleaning up installed gems...
