Given a Ruby program that uses a particular gem (e.g. term-ansicolor), how could I install the gem automatically, if required?
In other words, the program does:
require 'term/ansicolor'
and, in case the gem wasn’t install previously, I would like to install it and continue the program rather than getting an error:
LoadError: no such file to load -- term/ansicolor
from (irb):1:in `require'
from (irb):1
from :0
What would be the most appropriate method to achieve that?
