自定義寶石在/供應商/寶石不加載

Question

我最近決定採取一些功能，我已經在我的幾個Rails應用程序，並將其提取到引擎。我現在已經完成了引擎，並且正在嘗試將完成的寶石安裝到我的一個應用程序中。

這個特殊的寶石不是我想公開的東西，所以我打包了寶石gem build my_gem.gemspec，然後把打包好的寶石放到我的應用程序的vendor/gems文件夾中。然後，我將gem 'my_gem', '0.0.1', :path => 'vendor/gems'添加到我的gemfile並運行bundle install。

但不幸的是，Rails的似乎並沒有被加載的寶石，我似乎無法手動要求它：

$ bundle exec rails console --sandbox

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

難道我做錯了什麼？我該如何解決？

類型gem env檢查Ruby在尋找寶石的位置。

然後，您想要將您放入gem的目錄附加到GEM_PATH環境變量中。例如：

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

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

如果您使用的是Gemfile中，你也可以這樣做：

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

（你有你的寶石目錄中添加姓名到路徑）
