I bought a new Mac (:P) in these days, and I found that Leopard built- in rails 1.2.6 But it's rails 2.2.2 right now, so I upgraded Rubygems before I upgraded rails.. and after I upgraded Rubygems and Rails... I run "gem clean" and got the error message:
bash-3.2# gem clean Cleaning up installed gems... Attempting to uninstall rails-1.2.6 ERROR: While executing gem ... (Gem::InstallError) Unknown gem rails = 1.2.6
hmm.. I don't know how to solve it
Could anyone tell me how to solve it? thanks!
