Ruby on Windows7 - could not find gem

I'm setting up a ruby Apache Buildr on a fresh Windows 7 machine. I've installed Ruby, the DevKit and installed buildr via

    gem install buildr

wich all ran perfect. Until I tried to execute buildr, then I get an error.

    buildr compile

    C:/Ruby192/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find buildr (>= 0) amongst [atoulme-Antwrap-0.7.1, builder-2.1.2, buildr-1.4.5-x86-mswin32, buildr-as3-0.2.12, diff-lcs-1.1.2,highline-1.5.1, hoe-2.3.3, json_pure-1.4.3, minitar-0.5.3, minitest-1.6.0, net-sftp-2.0.4, net-ssh-2.0.23, rake-0.8.7, rdoc-2.5.8, rjb-1.3.2-x86-mswin32-60, rspec-2.1.0, rspec-core-2.1.0,rspec-expectations-2.1.0, rspec-mocks-2.1.0, rubyforge-2.0.3, rubygems-update-1.8.4, rubyzip-0.9.4, xml-simple-1.0.12] (Gem::LoadError)

    from C:/Ruby192/bin/buildr:18:in `<main>'

When I list all the gems with

   gem list buildr

Everything seems to match up, and this error makes no sense at all. enter image description here

Any ideas? Help would be great, I'm getting desperate now. :)

Solution

  • Had the same problem. I have Windows 7 x64 so installed again with gem install buildr --platform mswin64 and it worked.
