Morning got and update the Gem
Then try rails -v I got that:
command not found...
search for the solution by google...
then I use
locate gem | grep bin
found that gem is in "/usr/local/ruby/lib/ruby/gems/1.9.1/"
But the rails in "usr/bin" was ln to "/usr/local/ruby/lib/ruby/gems/1.8"
so I ln again use this:
sudo ln /usr/local/ruby/lib/ruby/gems/1.9.1/gems/rails /usr/bin/rails
bundle always got the same issue and with the same solution:
sudo ln /usr/local/ruby/lib/ruby/gems/1.9.1/gems/bundler-1.0.13/bin/bundle /usr/bin/bundle
