rubocop-lts / bundler-required_ruby_version-bug

Bugxample of bundler failing when required_ruby_version is restricted to single version

Geek Repo:Geek Repo

Github PK Tool:Github PK Tool

The purpose of this repository is to demonstrate a bug in bundler, both 2.3.14 and latest master @ 20e9b96b9, with various versions of Ruby.

The primary cause seems to be inclusion of a gem that has a severe required_ruby_version, and which precludes it from working for both the current library, and/or the current runtime.

I won't make a branch for each of the broken examples, as the matrix of affected combinations is pretty big. I will do one for current latest releases of bundler and ruby, and one for the HEADs.

HEADS

This branch contains the ERROR REPORT for ruby 3.2.0-preview1 + bundler 2.4.0.dev (ruby setup.rb @ 20e9b96b9 Merge pull request #5560 from mame/support-disabled_message).

NOTE: There is one combination that works: `ruby 3.2.0-preview1` + `bundler-2.4.0.dev (default gem)` # What working looks like 
bundle install

Resolving dependencies...
Bundler found conflicting requirements for the Ruby version:
  In Gemfile:
    bundler-required_ruby_version-bug was resolved to 0.1.0, which depends on
      Ruby (>= 2.4.0)

    rubocop-lts (~> 3.0) was resolved to 3.0.2, which depends on
      Ruby (< 2.1, >= 2.0.0)

When your local ruby is:

MRI 3.2.0-preview1

When your local bundler version is:

bundler-2.4.0.dev (default gem)

NOTE:

  • It doesn't work when you install rubygems from latest source and ruby setup.rb.
  • Somehow the included rubygems in 3.2.0-preview1 doesn't exhibit this bug, while latest released version, and latest source do.

The bug

When your local ruby is one of:

2.6.10
2.7.6
3.0.4
3.1.2
3.2.0-preview1

When local bundler version is:

2.3.14
2.4.0.dev (ruby setup.rb @ 20e9b96b9 Merge pull request #5560 from mame/support-disabled_message)
