我最近决定在我的几个Rails应用程序中使用一些功能并将其解压缩到引擎中。我现在已经完成了引擎,我正在尝试将完成的gem安装到我的一个应用程序中。
这个特殊的gem不是我想要公开的东西,所以我用gem build my_gem.gemspec
打包了gem,然后将打包的gem放在我的应用程序的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
。
不幸的是,Rails似乎没有加载宝石,我似乎无法手动要求它:
$ bundle exec rails console --sandbox
Loading development environment in sandbox (Rails 3.2.11)
Any modifications you make will be rolled back on exit

我做错了吗?我该如何解决这个问题?
编辑:这是我的宝石环境信息。

键入gem env
以检查Ruby搜索gem的位置。
然后,您希望将放置gem的目录附加到GEM_PATH环境变量中。 e.g:
export GEM_PATH="./vendor/gems:$GEM_PATH"
另请参阅:http://docs.rubygems.org/read/chapter/12
如果您使用的是Gemfile,也可以这样做:
gem 'my-gem', '0.0.1', :path => 'vendor/gems/my-gem'
(您必须将gem目录的名称添加到路径中)
