Rails on Fedora 20

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... Attempting to uninstall uglifier-1.3.0 Unable to uninstall uglifier-1.3.0:   Gem::InstallError: uglifier is not installed in GEM_HOME, try:   gem uninstall -i /usr/share/gems uglifier (..... for a number of packages) where [root@localhost new_app]# gem list | grep ugl* uglifier (2.5.3, 1.3.0)

your advise is welcome thanks mario
