Replication Case

gem install inspec fails

ERROR:  Error installing inspec:
ERROR: Failed to build gem native extension.

Full stack trace below.

Possible Solutions

I have suspicions this might be from the requirement to use ruby 2.2.

I am hoping not, as this means removing not only ruby, but puppet and a ton of other dependencies to manually install a later version of ruby, as the CentOS repos are still using 2.0.

    Building has failed. See above output for more information on the failure.

Just read 2.0 is end of life, so will close this as its not an issue for you to have to resolve.

@lukehinds the stacktrace and error isn't complete enough to determine what the problem is unfortunately. I suspect it's because gcc or other required libs aren't available for building the rainbow gem.

That said, with the InSpec release scheduled for today, our minimum Ruby version will be 2.1 because some dependencies (nokogiri, specifically) has a minimum version of 2.1, and Ruby 2.0 is end-of-life.

If you have an issue which requires you to keep Ruby 2.0 as your primary Ruby on your system, I'd like to recommend you install InSpec via our omnibus packages at https://downloads.chef.io/inspec. These packages are available for a number of OSs using the OS-native package format and include their own Ruby which will not conflict with the system Ruby.

Thank you for submitting this issue! I hope the omnibus packages can help you! If not, please ask for this issue to be reopened and we're happy to help troubleshoot as we're able.
