Issue/Introduction

When running install_gems.rb, the following error is shows:
E:/Ruby22-x64/lib/ruby/2.2.0/open3.rb:193:in 'spawn': Permission denied - E:\Ruby22-x64\bin install rubygems-update -v 2.7.6  --no-ri --no-rdoc (Errno::EACCES)
    from E:/Ruby22-x64/lib/ruby/2.2.0/open3.rb:193:in 'popen_run'
    from E:/Ruby22-x64/lib/ruby/2.2.0/open3.rb:93:in 'popen3'
    from E:/Connector/install_gems.rb:73:in 'run_command'
    from E:/Connector/install_gems.rb:39:in 'block (2 levels) in main'
    from E:/Connector/install_gems.rb:37:in 'each'
    from E:/Connector/install_gems.rb:37:in 'block in main'
    from E:/Connector/install_gems.rb:35:in 'chdir'
    from E:/Connector/install_gems.rb:35:in 'main'
    from E:/Connector/install_gems.rb:84:in '<main>'

Cause

This is caused by having GEM_COMMAND set incorrectly.  In the example above, the install_gems.rb is actually trying to execute E:\Ruby22-x64\bin, which is a folder and not executable.

You can verify the GEM_COMMAND with the following commands:
  • Windows:
set | findstr -i GEM_COMMAND
  • Linux:
env | grep -i GEM_COMMAND

Environment

Operating System
  • Linux
  • Mac 
  • Windows

Any of the Ruby based work item connectors
  • HP ALM Connector
  • Team Foundation Server (TFS) Connector
  • Jira Connector

 

Resolution

GEM_COMMAND should be set to point to the actual gem command in the ruby bin directory.

In the example above, ruby is installed in E:\Ruby22-x64.  The gem command is in the bin folder so GEM_COMMAND should be set to E:\Ruby22-x64\bin\gem
 

Additional Information

Windows
Any currently open command prompts will need to be closed in order to ensure that the updated environment variable is applied.

Make sure you are not overriding GEM_COMMAND in the User section of the environment variables as shown in the image below.  The System settings shows a valid configuration, however it is being overridden by the User variable which is incorrect.
