GemBundler Bug Report
1. bundle gem json1 # create a gem
2. cd json1
3. modify json1.gemspec to this:
# -*- encoding: utf-8 -*-
lib = File.expand_path('../lib', __FILE__)
$LOAD_PATH.unshift(lib) unless $LOAD_PATH.include?(lib)
require 'json1/version'
Gem::Specification.new do |gem|
gem.name = "json1"
gem.version = Json1::VERSION
gem.authors = ["Bachue Zhou"]
gem.email = ["bachue.shu@gmail.com"]
gem.description = %q{description}
gem.summary = %q{summary}
gem.homepage = ""
gem.files = `git ls-files`.split($/)
gem.executables = gem.files.grep(%r{^bin/}).map{ |f| File.basename(f) }
gem.test_files = gem.files.grep(%r{^(test|spec|features)/})
gem.require_paths = ["lib"]
gem.add_dependency 'json', '>= 1.7.3' # important
end
4. gem build json1.gemspec # build it, get json1-0.0.1.gem
5. cd ..
6. bundle gem json2 # create another gem
7. cd json2
8. modify json2.gemspec to this:
# -*- encoding: utf-8 -*-
lib = File.expand_path('../lib', __FILE__)
$LOAD_PATH.unshift(lib) unless $LOAD_PATH.include?(lib)
require 'json2/version'
Gem::Specification.new do |gem|
gem.name = "json2"
gem.version = Json2::VERSION
gem.authors = ["Bachue Zhou"]
gem.email = ["bachue.shu@gmail.com"]
gem.description = %q{description}
gem.summary = %q{summary}
gem.homepage = ""
gem.files = `git ls-files`.split($/)
gem.executables = gem.files.grep(%r{^bin/}).map{ |f| File.basename(f) }
gem.test_files = gem.files.grep(%r{^(test|spec|features)/})
gem.require_paths = ["lib"]
gem.add_dependency 'json', '<= 1.7.4' # important
end
9. gem build json2.gemspec # build it, get json2-0.0.1.gem
10. cd ..
11. mkdir test-project # create a project for test (not a rails project)
12. cd test-project
13. gem unpack ../json1/json1-0.0.1.gem
14. gem unpack ../json2/json2-0.0.1.gem # unpack these two gems to local
15. create a Gemfile, the content is:
source :rubygems
gem 'json1', '0.0.1', :path => 'json1-0.0.1/'
gem 'json2', '0.0.1', :path => 'json2-0.0.1/'
16. run "bundle install" # install gems from Gemfile
------------------
expected:
Fetching gem metadata from http://rubygems.org/..
Installing json (1.7.4) with native extensions
Using json1 (0.0.1) from source at json1-0.0.1/
Using json2 (0.0.1) from source at json2-0.0.1/
Using bundler (1.2.1)
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
------------------
actual:
Fetching gem metadata from http://rubygems.org/..
Bundler could not find compatible versions for gem "json":
In Gemfile:
json2 (= 0.0.1) ruby depends on
json (<= 1.7.4) ruby
json1 (= 0.0.1) ruby depends on
json (1.7.5)
------------------
# My explanation:
# Here I wrote 2 gems:
# json1, which depends on json >= 1.7.3
# json2, which depends on json <= 1.7.4
# And I created a project, use these 2 gems
# When I run "bundle install", bundler should install json plugin, whose version is >= 1.7.3 and <= 1.7.4
# So I think bundler should install json 1.7.4, but actually it failed.
------------------
