bundle install 工作，但 bundle-show 给出错误“rails.git 尚未签出。请运行`bundle install`”

Question

我最近更新了我们的 Gemfile 以在我们的 github 帐户上使用分叉的副本 rails。我们从 2.3-stable 分支（我将其称为 the_bugfix_branch）创建了一个自定义分支，并为每个 gem 添加了 gemspec，以使它们可以被 bundler 找到。

我的 Gemfile 有以下内容：

git 'git://github.com/ourgithub/rails.git', :branch => "the_bugfix_branch"  do
  # Note: load-order is essential for dependencies
  gem 'activesupport', '2.3.2' # this must go first
  gem 'actionpack',    '2.3.2' # this must go second
  gem 'actionmailer',  '2.3.2' 
  gem 'activerecord',  '2.3.2' 
  gem 'activeresource','2.3.2' 
  gem 'rails',         '2.3.2' # this must go last
end

bundle install 快​​乐地运行给我（在所有其余的 gem 输出中）：

Using actionpack (2.3.2) from git://github.com/ourgithub/rails.git (at the_bugfix_branch) 
Using actionmailer (2.3.2) from git://github.com/ourgithub/rails.git (at the_bugfix_branch) 
Using activesupport (2.3.2) from git://github.com/ourgithub/rails.git (at the_bugfix_branch) 
Using activerecord (2.3.2) from git://github.com/ourgithub/rails.git (at the_bugfix_branch) 
Using activeresource (2.3.2) from git://github.com/ourgithub/rails.git (at the_bugfix_branch) 
...
Using rails (2.3.2) from git://github.com/ourgithub/rails.git (at the_bugfix_branch)
...
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

然后我签入并提交 Gemfile.lock，其中包含：

GIT
  remote: git://github.com/ourgithub/rails.git
  revision: 3fc562f9b1def3ad9a7abbfd5ccfa713a6dbc39f
  branch: the_bugfix_branch
  specs:
    actionmailer (2.3.2)
      actionpack (= 2.3.2)
    actionpack (2.3.2)
      actionpack (= 2.3.2)
    activerecord (2.3.2)
      activesupport (= 2.3.2)
    activeresource (2.3.2)
      activesupport (= 2.3.2)
    activesupport (2.3.2)
    rails (2.3.2)
      actionmailer (= 2.3.2)
      actionpack (= 2.3.2)
      activerecord (= 2.3.2)
      activeresource (= 2.3.2)
      activesupport (= 2.3.2)
      rake (>= 0.8.3)

但是，如果我尝试启动服务器，它会告诉我：

The git source git://github.com/ourgithub/rails.git is not yet checked out. Please run `bundle install` before trying to start your application

如果我尝试bundle show rails 或bundle check，我也会收到完全相同的消息：

> bundle show rails
The git source git://github.com/ourgithub/rails.git is not yet checked out. Please run `bundle install` before trying to start your application
> bundle check
git://github.com/ourgithub/rails.git (at the_bugfix_branch) is not checked out. Please run `bundle install`

如果我尝试bundle install --deployment（只是为了好玩）它会给出：

> bundle install --deployment
You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
updated Gemfile.lock to version control.

You have added to the Gemfile:
* source: git://github.com/ourgithub/rails.git (at the_bugfix_branch)

You have deleted from the Gemfile:
* source: git://github.com/ourgithub/rails.git (at the_bugfix_branch)

You have changed in the Gemfile:
* activeresource from `git://github.com/ourgithub/rails.git (at the_bugfix_branch)` to `no specified source`
* activerecord from `git://github.com/ourgithub/rails.git (at the_bugfix_branch)` to `no specified source`
* actionmailer from `git://github.com/ourgithub/rails.git (at the_bugfix_branch)` to `no specified source`
* actionpack from `git://github.com/ourgithub/rails.git (at the_bugfix_branch)` to `no specified source`
* activesupport from `git://github.com/ourgithub/rails.git (at the_bugfix_branch)` to `no specified source`
* rails from `git://github.com/ourgithub/rails.git (at the_bugfix_branch)` to `no specified source`

我显然没有只是更改了我的 Gemfile，而且自从我将这些东西添加到 Gemfile 以来，我肯定运行了 bundle install。

我已经用谷歌搜索了 “尚未签出。请在尝试启动您的应用程序之前运行 bundle install” 并且所有 “bundle install 将不起作用” 我能找到的问题似乎是 “只需运行 bundle install 然后检查您的 Gemfile.lock 副本”...我显然已经完成了。它们也往往是关于捆绑安装在生产中失败的问题，但我的在开发中也以这种方式失败。

我不认为这是一个简单的 Gemfile/Gemfile.lock 不匹配问题！

一些谷歌结果告诉我尝试删除 .bundle/config 并再次运行它。我已经尝试过同样的（缺乏）效果。

具体来说，在重新运行捆绑安装之前，我浏览了本故障排除指南的所有 rm -rf 行：https://github.com/carlhuda/bundler/blob/master/ISSUES.md。

错误消息没有变化。

有什么想法吗？

原来我错了。

解决方案是删除 Gemfile 中的版本号，并明确使用分支：

git 'git://github.com/ourgithub/rails.git', :branch => "the_bugfix_branch"  do
  # Note: load-order is essential for dependencies
  gem 'activesupport', :branch => "the_bugfix_branch" # this must go first
  gem 'actionpack',    :branch => "the_bugfix_branch" # this must go second
  gem 'actionmailer',  :branch => "the_bugfix_branch" 
  gem 'activerecord',  :branch => "the_bugfix_branch" 
  gem 'activeresource',:branch => "the_bugfix_branch" 
  gem 'rails',         :branch => "the_bugfix_branch" # this must go last
end

bundler 一方面对版本号感到困惑，另一方面对分支感到困惑。

为列出的每个 gem 显式设置分支，似乎终于成功了！
