Error while executing "fastlane provision" command

Question

I'm trying to integrate FastLane for automatic app submission to app store. I am following this tutorial, but while Creating Certificates and Provisioning Profiles using "fastlane provision" command I'm getting below issues.

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:135:in `require': cannot load such file -- gh_inspector (LoadError)
