Damn, it was so simple... to update the gemfile, you only got to execute these two command lines:
gem source -r https://rubygems.org/
gem source -a http://rubygems.org/
Then you can execute your installation normally:
gem install rails
Question
I'm trying to install rails but I get a "marshal data too short" error. I read in this question ( bundle update fails : marshal data too short ) that I can update the Gemfile to make it work.
My problem is that I really have no idea how to modify this "Gemfile".
Thx.

OTHER TIPS
Go to the root of your application, and look for Gemfile. The root of the application is where you run rails server from, in case you were wondering :)
Open Gemfile using your favorite text editor, and try changing the rubygems source from HTTP to HTTPS.
Locate the following:
source 'http://rubygems.org'
Replace it with:
source 'https://rubygems.org'
