And then followed the updated one as well and still get issues, i cant seem to get gem to install correctly? And or install correctly. I have sort of pin pointed the issue down, i get an error like this each time i attempt to use gem. /usr/local/lib/ruby/site\_ruby/1.9.0/rubygems/package.rb:386:in `alias_method': undefined method `is\_file’ for class `Gem::Package::TarReader::Entry' (NameError) from /usr/local/lib/ruby/site_ruby/1.9.0/rubygems/package.rb:386:in `class:Entry’ from /usr/local/lib/ruby/site\_ruby/1.9.0/rubygems/package.rb:322:in `' from /usr/local/lib/ruby/site_ruby/1.9.0/rubygems/package.rb:310:in `module:Package’ from /usr/local/lib/ruby/site\_ruby/1.9.0/rubygems/package.rb:43:in `' from /usr/local/lib/ruby/site_ruby/1.9.0/rubygems/custom_require.rb:27:in `gem\_original\_require’ from /usr/local/lib/ruby/site\_ruby/1.9.0/rubygems/custom\_require.rb:27:in `require' from /usr/local/lib/ruby/site_ruby/1.9.0/rubygems/builder.rb:7:in `\’ from /usr/local/lib/ruby/site\_ruby/1.9.0/rubygems/custom\_require.rb:27:in `gem_original_require' from /usr/local/lib/ruby/site_ruby/1.9.0/rubygems/custom_require.rb:27:in `require’ from /usr/local/lib/ruby/site\_ruby/1.9.0/rubygems.rb:110:in `manage_gems' from gem_prelude.rb:182:in `method\_missing’ from /usr/local/bin/gem:10:in `’ I notice it is looking to point to /1.9.0/ but when i browse to that folder i have 1.8.

You already have a version of ruby (1.8.6) and RubyGems installed if you’re on OS X 10.5, /usr/bin/ruby You’ll want to update RubyGems for Apple’s ruby though. > I have sort of pin pointed the issue down, i get an error like this > each > time i attempt to use gem. > > /usr/local/lib/ruby/site\_ruby/1.9.0/rubygems/package.rb:386:in > `alias_method': undefined method`is\_file’ for class > `Gem:📦:TarReader::Entry’ (NameError) 1.9.1 is the latest version of ruby and comes with the latest RubyGems. You probably have a prerelease version of 1.9.0 installed that has a broken RubyGems. I imagine that `which ruby` will report /usr/local/bin/ruby, and `ruby -v` will report 1.9.0. If you want to use ruby 1.9 you should remove your current install of 1.9.0 in /usr/local and configure 1.9.1 with its own suffix: ./configure --program-suffix=19 So you get /usr/local/bin/ruby19 which won’t conflict with the 1.8.6 install you have from Apple. ---

If i try ruby -command- it gives me this ruby: No such file or directory – help (LoadError)
