Strange bundle update issue: disappearing net-pop (0.1.2) dependency

I have a strange bundle update issue with the dependency of net-pop.

I manually updated all gems via bundle update GEM. Everything works so far. My CI builds and tests jobs are green.

But:
When I now run bundle update, my Gemfile.lock will be changed and the dependency ‘net-protocol’ of ‘net-pop’ gets deleted. Nothing else get changed.

Gemfile.lock

Of course, my CI build job will fail with the error message:

47.64 Downloading net-pop-0.1.2 revealed dependencies not in the API or the lockfile
47.64 (net-protocol (>= 0)).
47.64 Running `bundle update net-pop` should fix the problem.

Running bundle update net-pop does not help.

The gemspec file of net-pop is correct https://github.com/ruby/net-pop/blob/master/net-pop.gemspec#L31

Currently, the only solution is to manually modify the Gemfile.lock and to re-add the missing line.

I do not understand what’s going on.

Gemfile

and bundle update afterwards deletes the net-protocol line.

Solution

  • The issue is reproducible with ruby v3.3.3 only:

    # Gemfile

source "https://rubygems.org"

gem "net-pop", require: false

    I traced it all the way up to ruby installation. net-pop is a bundled gem it gets installed with ruby, this process generates a gemspec file:

    # ~/.rbenv/versions/3.3.3/lib/ruby/gems/3.3.0/specifications/net-pop-0.1.2.gemspec

# -*- encoding: utf-8 -*-
# stub: net-pop 0.1.2 ruby lib

Gem::Specification.new do |s|
  s.name = "net-pop".freeze
  s.version = "0.1.2".freeze

  s.required_rubygems_version = Gem::Requirement.new(">= 0".freeze) if s.respond_to? :required_rubygems_version=
  s.metadata = { "homepage_uri" => "https://github.com/ruby/net-pop", "source_code_uri" => "https://github.com/ruby/net-pop" } if s.respond_to? :metadata=
  s.require_paths = ["lib".freeze]
  s.authors = ["Yukihiro Matsumoto".freeze]
  s.bindir = "exe".freeze
  s.date = "2024-06-12"
  s.description = "Ruby client library for POP3.".freeze
  s.email = ["matz@ruby-lang.org".freeze]
  s.homepage = "https://github.com/ruby/net-pop".freeze
  s.licenses = ["Ruby".freeze, "BSD-2-Clause".freeze]
  s.rubygems_version = "3.3.5".freeze
  s.summary = "Ruby client library for POP3.".freeze

  s.installed_by_version = "3.5.11".freeze if s.respond_to? :installed_by_version
end

    There are two lines missing, including the dependency:

    s.specification_version = 4
s.add_runtime_dependency(%q<net-protocol>.freeze, [">= 0".freeze])

    When you run bundle, that file is used to lookup all the information for a gem and generate a Gemfile.lock.

    Workarounds

    Remove that gemspec file and run bundle update or gem install again:

    rm ~/.rbenv/versions/3.3.3/lib/ruby/gems/3.3.0/specifications/net-pop-0.1.2.gemspec
bundle update

    or from irb:

    File.delete(Gem::Specification.find_by_name("net-pop").spec_file)
Gem.install("net-pop")

    or uninstall it first:

    gem uninstall net-pop
gem install net-pop

    or @Schneems' solution that also works on Heroku:

    # Gemfile

gem "net-pop", github: "ruby/net-pop"

    which will recreate gemspec file correctly:

    # ~/.rbenv/versions/3.3.3/lib/ruby/gems/3.3.0/specifications/net-pop-0.1.2.gemspec

# -*- encoding: utf-8 -*-
# stub: net-pop 0.1.2 ruby lib

Gem::Specification.new do |s|
  s.name = "net-pop".freeze
  s.version = "0.1.2".freeze

  s.required_rubygems_version = Gem::Requirement.new(">= 0".freeze) if s.respond_to? :required_rubygems_version=
  s.metadata = { "homepage_uri" => "https://github.com/ruby/net-pop", "source_code_uri" => "https://github.com/ruby/net-pop" } if s.respond_to? :metadata=
  s.require_paths = ["lib".freeze]
  s.authors = ["Yukihiro Matsumoto".freeze]
  s.bindir = "exe".freeze
  s.date = "2022-09-28"
  s.description = "Ruby client library for POP3.".freeze
  s.email = ["matz@ruby-lang.org".freeze]
  s.homepage = "https://github.com/ruby/net-pop".freeze
  s.licenses = ["Ruby".freeze, "BSD-2-Clause".freeze]
  s.rubygems_version = "3.4.0.dev".freeze
  s.summary = "Ruby client library for POP3.".freeze

  s.installed_by_version = "3.5.11".freeze if s.respond_to? :installed_by_version

  s.specification_version = 4

  s.add_runtime_dependency(%q<net-protocol>.freeze, [">= 0".freeze])
end

    Looks like gemspec files are part of the ruby releases, so it's just broken out of the box:
