Rubygems: Regression of bundler#7536 - bundler/inline breaks

Created on 15 Jun 2020 · 2Comments · Source: rubygems/rubygems

I'm experiencing what seems to be a regression of https://github.com/rubygems/bundler/issues/7536

Do you have a reproduction script?

# inline.rb
require "bundler/inline"
gemfile do
  source "https://rubygems.org"
  gem "capistrano", require: false
end

require "capistrano/all"

Just drop this into a location without a Gemfile and run it.

What are you trying to accomplish?

I'm attempting to use bundler/inline without a Gemfile. This was previously broken in Bundler 2.1.0, fixed in 2.1.4, and seems to have regressed somehow over this weekend. Both myself and a coworker have reproduced the error in separate environments.

What command did you run?

ruby inline.rb
What were you expecting to happen?

Capistrano should be loaded.
What actually happened?

Bundler throws an exception:

Hi!

This seems not a regression, but a separate bug. Something must've changed in capistrano (in net-ssh actually), and now a gem is failing to be activated. When handling that error, bundler is assuming that there's a Gemfile and crashing here:

https://github.com/rubygems/rubygems/blob/ea2376928988c8124bba661e0754d7a00dcab347/bundler/lib/bundler/rubygems_integration.rb#L323

I will try to fix this.
