Avoid dependency from a gem on the commandline

Ruby
1

Hi

Right now gem will refuse to install a program if a dependency is not
met.

Is there a way to ignore that and still attempt an installation?

Specifically this is a gem that I myself wrote anyway and I now that the
project will still work partially, yet I can’t seem to get gem to try to
download anyway. I need like an option ‘still attempt to install it’.

Have you tried this (from ‘gem help install’):

-f, --[no-]force                 Force gem to install, bypassing

dependency
checks

Jesus.

Thanks! That seems to work.

Hmm… while installing works, running actually fails.

require ‘diamond_shell’

"Gem::LoadError: Could not find chemistry (>= 1.0.0) amongst "

This is a problem. I know that chemistry is not mandatory at all, yet it
seems as if gem will try to always ensure that it is available. And if
it is not available, it will refuse to run.

At home on my linux machine it works just fine for me. I don’t use gem
directly though, I use setup.rb.

I am here on a windows machine right now and it is bad that gem refuses
to continue … I wrote the project myself, I know that chemistry is not
mandatory for all components.

Unfortunately I also can not modify rubygems or ruby on that windows
machine here, so I guess I am stuck. :frowning:

I’m not really a fan of this behavior, either, but it is what it is.

I don’t think you need to modify rubygems or ruby, just modify the gem
itself and remove the ‘chemistry’ dependency.
