I get an error when i run:
vagrant@vagrantup:~$ sudo gem list
ERROR: Loading command: list (LoadError)
no such file to load -- zlib
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::ListCommand
Even if I don’t use sudo I get the same error message.
It’s on Ubuntu 10.4 and I have installed zlib libraries:
vagrant@vagrantup:~$ sudo aptitude search zlib

Im using http://www.vagrantup.com and the error comes after i have installed rvm.
What could the problem be?
How was Ruby installed? If Ruby was installed without zlib support, that would be the problem.
You can read my article here on installing RVM on Ubuntu. You must have both zlib and the zlib-dev packages installed before compiling Ruby (along with some other packages from Ubuntu). You’ll probably just need to install these and re-compile Ruby.
