自定义宝石在/供应商/宝石不加载

Question

我最近决定采取一些功能，我已经在我的几个Rails应用程序，并将其提取到引擎。我现在已经完成了引擎，并且正在尝试将完成的宝石安装到我的一个应用程序中。

这个特殊的宝石不是我想公开的东西，所以我打包了宝石gem build my_gem.gemspec，然后把打包好的宝石放到我的应用程序的vendor/gems文件夹中。然后，我将gem 'my_gem', '0.0.1', :path => 'vendor/gems'添加到我的gemfile并运行bundle install。

但不幸的是，Rails的似乎并没有被加载的宝石，我似乎无法手动要求它：

$ bundle exec rails console --sandbox

     from script/rails:6:in `require' 
     from script/rails:6:in `<main>' 

难道我做错了什么？我该如何解决？

类型gem env检查Ruby在寻找宝石的位置。

然后，您想要将您放入gem的目录附加到GEM_PATH环境变量中。例如：

export GEM_PATH="./vendor/gems:$GEM_PATH" 

参见：http://docs.rubygems.org/read/chapter/12

如果您使用的是Gemfile中，你也可以这样做：

gem 'my-gem', '0.0.1', :path => 'vendor/gems/my-gem' 

（你有你的宝石目录中添加姓名到路径）
