install rails on Ubuntu fails, probably due to missing bundler gem

I cannot install rails on ubuntu 11.4. I tested this twice on my workstation and then on a开发者_如何学C virtual machine freshly installed. Rails install will report error.

Hint: Also I cannot find the bundle command which should be installed by 'gem install bundler'

I skipped from the log all successful output.

Not sure what your exact issue is, but in my experience ruby packages are nothing but trouble. Try building ruby from source or better yet, use RVM. Since I switched I stopped having most of my weird errors. My 2 cents

As Kelend said, use RubyVersionManager:
