Ruby gem failure on installing ri documentation

Question

I am trying to install GitLabHQ on my Debian 6.0.4 machine. It is a fresh install of April 13th, 2012. Now I have come to the point where I need some installs to be done by Ruby gem. In particular:

gem install bundler

This reveals the following error:

Successfully installed bundler-1.1.3
1 gem installed
Installing ri documentation for bundler-1.1.3...
ERROR:  While executing gem ... (ArgumentError)
undefined class/module Encoding

Then I tried to rebuild the Ruby packages with

gem pristine --all

This did not help. Here is list of the Ruby packages installed:

Even though the bundler appears in the list, it does not seem to have been installed properly.

I hope someone can help me on this because I really need GitLabHQ to be working.

Answer 1

Not a fix, really, but a workaround: Put this line:

gem: --no-rdoc --no-ri

into a file named ~/.gemrc to skip installation of rdoc and ri documentation (which you may not want on your system anyway - it will speed up the install process quite a bit).
