(Debian squeeze) rvm version: 1.10.0
I have just installed ruby 1.9.2-p290 using "rvm install 1.9.2" and made it default. However, I am getting this error when trying to install rails using rubygems. "gem install rails" worked fine on my system ruby installation.
root:/usr/bin# rvm list
=> ruby-1.9.2-p290 [ i686 ]
root:/usr/bin# rvm current ruby-1.9.2-p290 root:/usr/bin# gem list
* LOCAL GEMS *
root:/usr/bin# gem install rails ERROR: Loading command: install (LoadError) no such file to load -- zlib
ERROR: While executing gem ... (NameError) uninitialized constant Gem::Commands::InstallCommand
I have tried the instructions on this other page: https://stackoverflow.com/questions/2441248/rvm-ruby-1-9-1-troubles, (apt-get install zlib, reinstalling 1.9.2 on rvm), but that didn't seem to work. Any ideas of what might be the root problem?
