From: RichardOnRails Date: 2008-08-05T08:08:35+09:00 Subject: "gem install rails –r" => (URI::InvalidURIError) Hi All, I installed Ruby 1.9.0-03 (ruby 1.9.0 (2008-07-25 revision 18217) [i386-mswin32]) over WinXP/SP2 a few days ago. It works great. That installation included gem 1.2.0.1824. I searched for a Rails gem and got: K:\_Utilities\Ruby>gem list rails -r *** REMOTE GEMS *** rails (2.1.0) [snip] I tried a number of permutations/combinations of: gem install rails –r They all failed with: ERROR: While executing gem ... (URI::InvalidURIError) bad URI(is not URI?): Gem under my Ruby 1.8.6 installation was working fine a while back. My Firefox 2.0 browser is working fine. Any idea what the problem might be? Thanks in Advance, Richard
