Thanks.

Here is a script called gemcmd. This script is to be used in place of
the gem command. It will choose the proper platform and will install
the latest version of the requested gem available with no interaction
so it is suitable to be called from scripts.

‘gemcmd’ - A non-interactive version of ‘gem’.

We need to preserve the original ARGV to use for passing gem options
to source gems. If there is a – in the line, strip all options after
it…its for the source building process.
args = !ARGV.include?(“–”) ? ARGV.clone : ARGV[0…ARGV.index(“–”)]
Gem::GemRunner.new.run(args)
