Ruby193 folder Structure ( Missing )

Answer 1

As Prakash Murthy said, It was missing ruby-wmi files. Thought it will help if anyone get stuck again

I did run these commands

C:\> gem install win32-open3 ruby-wmi windows-api windows-pr --no-rdoc --no-ri --verbose
C:\> gem install rdp-ruby-wmi

Got one more error

C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in require': cannot load such file -- win32/service (LoadError)

So i would recommend

(i) check gem installed ( in CMD )

gem list

this will pointout missing gems, in my case win32/service was misisng

(ii) gem install win32-service

check gem list again to make sure & should fix the problems.

Answer 2

Newer versions of Chef do not use ruby-wmi, so you should not need the gem. I got this error while trying to run test kitchen, and I have tried the solutions above but they didn't work.

This worked for me:

• Uninstall and re-install Vagrant
• Delete C:\Users\USERNAME.vagrant.d\gems folder
• Delete C:\Users\USERNAME.vagrant.d\plugins.json file

After that kitchen runs fine.

Answer 3

The error message cannot load such file -- ruby-wmi (LoadError) is coming up because chef-client cannot find the required gems.

This issue is addressed on the Opscode/Chef wiki page on Common Errors.

As mentioned there, install the required gems with the following commands:

C:\> gem install win32-open3 ruby-wmi windows-api windows-pr --no-rdoc --no-ri --verbose
C:\> gem install rdp-ruby-wmi
