如何在Gemfile中指定本地gem ?

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?

我希望邦德勒能装载当地的宝石。有选择的余地吗?还是必须将gem文件夹移动到.bundle目录中?

I believe you can do this:

我相信你可以做到:

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 only by using the following configuration option:

除了指定路径(如Jimmy提到的)，您还可以通过以下配置选项强制Bundler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gems或gem和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:

但是请注意，这只在您已经在使用git作为依赖项时有效，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.

就像在文档中看到的。

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.

但我不确定是否每个人都需要执行这两个步骤。

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

为了在Rails项目中使用本地gem存储库，请遵循以下步骤:

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

检查您的gem文件夹是否是git存储库(命令在gem文件夹中执行)
```
git rev-parse --is-inside-work-tree
```
Getting repository path (the command is executed in the gem folder)

获取存储库路径(在gem文件夹中执行命令)
```
git rev-parse --show-toplevel
```
Setting up a local override for the rails application

为rails应用程序设置一个本地覆盖。
```
bundle config local.GEM_NAME /path/to/local/git/repository
```
where GEM_NAME is the name of your gem and /path/to/local/git/repository is the output of the command in point 2

GEM_NAME是您的gem的名称，/path/to/local/git/repository是第2点命令的输出吗
In your application Gemfile add the following line:

在您的应用程序Gemfile中添加以下一行:
```
gem 'GEM_NAME', :github => 'GEM_NAME/GEM_NAME', :branch => 'master'
```
Running bundle install should give something like this:

运行bundle安装应该给出如下内容:
```
Using GEM_NAME (0.0.1) from git://github.com/GEM_NAME/GEM_NAME.git (at /path/to/local/git/repository) 
```
where GEM_NAME is the name of your gem and /path/to/local/git/repository from point 2

在第2点，GEM_NAME是您的gem和/path/to/local/git/存储库的名称?
Finally, run bundle list, not gem list and you should see something like this:

最后，运行bundle list，而不是gem list，您应该看到如下内容:
```
GEM_NAME (0.0.1 5a68b88)
```
where GEM_NAME is the name of your gem

宝石的名字在哪里

A few important cases I am observing using:

我正在观察的几个重要案例是:

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 RubyMine is not showing local gems as an external library. More information about the bug can be found here and here
看来RubyMine并没有将本地gem作为外部库来展示。关于这个bug的更多信息可以在这里和这里找到
When I am changing something in the local gem, in order to be loaded in the rails application I should stop/start the rails server
当我在本地gem中更改某些内容时，为了在rails应用程序中加载，我应该停止/启动rails服务器
If I am changing the version of the gem, stopping/starting the Rails server gives me an error. In order to fix it, I am specifying the gem version in the rails application Gemfile like this:

如果我正在更改gem的版本，那么停止/启动Rails服务器会给我一个错误。为了修复它，我在rails应用程序Gemfile中指定了gem版本，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 them in this article.

您可以引用gems with source: source: https://source.com, git repository (:github => 'git/url')，以及local path:path => '…/path/gem_name'。在本文中，您可以了解关于Gemfiles的更多信息，以及如何使用它们。

If you want the branch too:
