为Rails项目分配一个gem [英] Forking a gem for a Rails project

问题描述

在这种情况下，我发现自己已经两次了：我在我的系统上安装了一个gem，并从我的Rails项目开始使用它。最终，我需要对该宝石进行一些更改。我应该如何继续？

理想情况下，我想查看某个地方的gem源代码，比如〜/ third_party / gems，使用它并让我的Rails项目使用，而不是。这是可能的吗？

在所有情况下，gem都在github上，所以我可能会在github上克隆它，让我的机会和维护自己的分支。我想那时我会直接用我的服务器上的gem install来安装那个分支。这是否有意义？

解决方案

今天这对Bundler来说很容易。您创建一个gem的本地副本，然后而不是做

  gemwhatever
 
 gemwhatever，：path => / home / pupeno / whatever
  
运行软件包安装后，将从该目录中选取gem。即使您修改了某些内容，您只需重新加载即可重新启动Rails。
 
 
 
如果您需要使用自己的宝石，你在Github上或类似的Gemfile上做了一个分支： 
 
 
  gemwhatever，：：git = > [e-mail]：/pupeno/whatever.git
  
就是这样。这很简单，直接，美丽。
 
I've found myself twice in this situation: I install a gem on my system and start using it from my Rails project. Eventually I need to make some changes to that gem. How should I proceed?

Ideally I'd like to check out the source code of that gem somewhere, like ~/third_party/gems, work on it and have my Rails project use that instead. Is that possible?

In all the cases the gems were at github so I would probably for it at github, clone it, make my chances and maintain my own branch. I suppose then I would install that branch directly with gem install on my server. Does that make sense?
解决方案
Today this is pretty easy to do with Bundler. You make a local copy of the gem and then instead of doing
gem "whatever"
in your Gemfile, you do:
gem "whatever", :path => "/home/pupeno/whatever"
After running bundle install, the gem is picked from that directory. Even if you modify something in there, all you need to do to re-load it is restart Rails.

If you need to deploy an application using your own changes of a Gem, you make a fork, on Github or similar and on the Gemfile you do:
gem "whatever", :git => "[e-mail]:/pupeno/whatever.git"
and that's it. It's simple, straightforward and beautiful.
