Can't find rake on Ruby Rails Install

C:\Windows\system32>gem install rake

C:\Windows\system32>rake
C:/Program Files (x86)/Ruby192/lib/ruby/1.9.1/rubygems.rb:340:in `bin_path': can
't find executable rake for rake-0.8.7 (Gem::Exception)
        from C:/Program Files (x86)/Ruby192/bin/rake:19:in `<main>'

C:\Windows\system32>

Why can't my system find the rake command? Where should I start debugging the problem?

Update 1

I'm using ruby 1.9.2 and installed it using the ruby installer for windows (http://rubyinstaller.org/)

Answer 1

This issue is a problem of Ruby 1.9.2 bundled version of Rake. You will need to remove the included rake.gemspec from the gem specification folder.

See this thread at RubyInstaller group, and specifically this link from Ruby-Forums for the solution.

BTW: a recommendation: avoid installing Ruby into path with spaces (Program Files). I forsee lot of problems with your installation in the future.
