Error "set_paths: undefined method uid for nil:NilClass (NoMethodError)" while installing RubyGems on Vista

I get the following error when attempting to install RubyGems. I've tried Googling but have had no luck there. Has anybody encountered and resolved this issue before?

I have Ruby 1.8.6 installed on my laptop running Windows Vista.

Solution

  • I assume you're not trying to install under cygwin; that install is meant for unix-like operating systems. Edit: (Actually, from the log above it looks like there is some Windows-specific stuff being run... perhaps you're running into a UAC protection issue?)

    If you just use the Windows ruby one-click installer, it includes rubygems. If you're not getting the rubygems functionality, you may need to require "rubygems" in your script, or add -rubygems to your RUBYOPT environment variable. (You can also require rubygems from the command line with ruby -rubygems myscript.rb.

    Are you trying to install it separately for some other reason?
