Madhu - I would suggest checking with Brandon on this since he made changes in this area recently.

Comment 4 Brandon Dunne 2017-11-30 20:43:47 UTC
Ncatling, you need to install the "mime-types" gem on the system.

Comment 5 mkanoor 2017-12-01 18:41:57 UTC
We are working on fixing the build so the user doesn't have to install mime-types gem.

Comment 6 Nick LaMuro 2017-12-04 20:08:59 UTC along with is one proposed solution for the problem.

That said, we are probably going to go with the more simple solution of just installing `mime-types` in the gem directory.  This will not get used when loading the appliance, but then will be available in automation scripts.

    Install 'mime-types' outside of bundle, as it's needed to load 'rest-client'
    in irb/automate.  For bundle, we override with local path 'mime-types-redirector'

Verified on that require 'rest-client' doesn't fail with Gem::LoadError within irb.
