Ruby-on-rails 如何在我的 Gemfile 中指定本地 gem？

How can I specify a local gem in my Gemfile?

提问by picardo

I'd like Bundler to load a local gem. Is there an option for that? Or do I have to move the gem folder into the .bundle directory?

我希望 Bundler 加载本地 gem。有没有选择？或者我是否必须将 gem 文件夹移动到 .bundle 目录中？

I believe you can do this:

我相信你可以这样做：

gem "foo", path: "/path/to/foo"

In addition to specifying the path (as Jimmy mentioned) you can also force Bundler to use a local gem for your environment onlyby using the following configuration option:

除了指定路径（如 Jimmy 提到的），您还可以强制 Bundler仅通过使用以下配置选项为您的环境使用本地 gem ：

$ bundle config local.GEM_NAME /path/to/local/git/repository

This is extremely helpful if you're developing two gems or a gem and a rails app side-by-side.

如果您同时开发两个 gem 或一个 gem 和一个 rails 应用程序，这将非常有用。

Note though, that this only works when you're already using git for your dependency, for example:

但请注意，这仅在您已经将 git 用于您的依赖项时才有效，例如：

# In Gemfile
gem 'rack', :github => 'rack/rack', :branch => 'master'

# In your terminal
$ bundle config local.rack ~/Work/git/rack

As seen on the docs.

如文档所示。

You can also reference a local gem with git if you happen to be working on it.

如果您碰巧正在处理它，您还可以使用 git 引用本地 gem。

gem 'foo',
  :git => '/Path/to/local/git/repo',
  :branch => 'my-feature-branch'

Then, if it changes I run

然后，如果它改变我运行

bundle exec gem uninstall foo
bundle update foo

But I am not sure everyone needs to run these two steps.

但我不确定每个人都需要运行这两个步骤。

In order to use local gem repository in a Rails project, follow the steps below:

要在 Rails 项目中使用本地 gem 存储库，请按照以下步骤操作：

1. Check if your gem folder is a git repository (the command is executed in the gem folder)

   git rev-parse --is-inside-work-tree
   

2. Getting repository path (the command is executed in the gem folder)

   git rev-parse --show-toplevel
   

3. Setting up a local override for the rails application

   bundle config local.GEM_NAME /path/to/local/git/repository
   

   where GEM_NAMEis the name of your gem and /path/to/local/git/repositoryis the output of the command in point 2

4. In your application Gemfileadd the following line:

   gem 'GEM_NAME', :github => 'GEM_NAME/GEM_NAME', :branch => 'master'
   

5. Running bundle installshould give something like this:

   Using GEM_NAME (0.0.1) from git://github.com/GEM_NAME/GEM_NAME.git (at /path/to/local/git/repository) 
   

   where GEM_NAMEis the name of your gem and /path/to/local/git/repositoryfrom point 2

6. Finally, run bundle list, not gem listand you should see something like this:

   GEM_NAME (0.0.1 5a68b88)
   

   where GEM_NAMEis the name of your gem

1. 检查你的gem文件夹是否是git仓库（命令在gem文件夹中执行）

   git rev-parse --is-inside-work-tree
   

2. 获取仓库路径（命令在gem文件夹中执行）

   git rev-parse --show-toplevel
   

3. 为 rails 应用程序设置本地覆盖

   bundle config local.GEM_NAME /path/to/local/git/repository
   

   哪里GEM_NAME是你的 gem 的名称，/path/to/local/git/repository是命令的输出点2

4. 在您的应用程序中Gemfile添加以下行：

   gem 'GEM_NAME', :github => 'GEM_NAME/GEM_NAME', :branch => 'master'
   

5. 运行bundle install应该给出这样的东西：

   Using GEM_NAME (0.0.1) from git://github.com/GEM_NAME/GEM_NAME.git (at /path/to/local/git/repository) 
   

   GEM_NAME您的宝石名称和/path/to/local/git/repository起点在哪里2

6. 最后，运行bundle list, not gem list，您应该会看到如下内容：

   GEM_NAME (0.0.1 5a68b88)
   

   GEM_NAME你的宝石的名字在哪里

A few important cases I am observing using:

我观察到的几个重要案例使用：

Rails 4.0.2  
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux] 
Ubuntu 13.10  
RubyMine 6.0.3

• It seems RubyMineis not showing local gems as an external library. More information about the bug can be found hereand here
• When I am changing something in the local gem, in order to be loaded in the rails application I should stop/startthe rails server

• If I am changing the versionof the gem, stopping/startingthe Rails server gives me an error. In order to fix it, I am specifying the gem version in the rails application Gemfilelike this:

  gem 'GEM_NAME', '0.0.2', :github => 'GEM_NAME/GEM_NAME', :branch => 'master'
  

• 似乎RubyMine没有将本地 gem 显示为外部库。可以在此处和此处找到有关该错误的更多信息
• 当我在本地 gem 中更改某些内容时，为了加载到 rails 应用程序中，我应该stop/start使用 rails 服务器

• 如果我正在更改versiongem 的，stopping/startingRails 服务器会给我一个错误。为了修复它，我在 rails 应用程序中指定 gem 版本，Gemfile如下所示：

  gem 'GEM_NAME', '0.0.2', :github => 'GEM_NAME/GEM_NAME', :branch => 'master'

You can reference gems with source: source: 'https://source.com', git repository (:github => 'git/url')and with local path :path => '.../path/gem_name'.
You can learn more about Gemfiles and how to use themin this article.

您可以使用 source:source: 'https://source.com', git repository (:github => 'git/url')和 local path引用 gems :path => '.../path/gem_name'。

If you want the branch too:

如果你也想要分支：

gem 'foo', path: "point/to/your/path", branch: "branch-name"
