#gem_package(name, version = nil) ⇒ Object

In recent versions of the AmazonLinux2 cfnbootstrap, , the package command doesnt work with updated versions of rubygems. Get this error

invalid option: --no-ri

More details: gist.github.com/tongueroo/569878afdc7eb904490b9ee8b03f304f

Found the cfnbootstrap version by looking at the source on 2020-03-21 in

$ cat /usr/lib/python2.7/site-packages/cfnbootstrap/public_constants.py
_release = '31'
_version = '1.4-' + _release

There is no way to get the version from the /opt/aws/bin/cfn-init command.

We work around this be using the command instruction and use the gem install and list commands.

$ gem list tilt -e -i -v 1.4.0
false # also $? is 1
$ gem list tilt -e -i -v 1.4.1
true # also $? is 0
$
