Question

当使用RVM和git gems安装'bundle install'时，'gem list'无法找到gems。

4

我目前正在尝试运行"bundle install"来安装一个基于git的gem，使用Gemfile，并且使用最新版本的RVM（1.14.3）来使用ruby/其他ruby命令而不用bundler。我认为问题的原因是bundler将git gem安装到.rvm/gems/ruby-1.9.3-p194@something/bundler/gems中，而所有其他gems都安装在.rvm/gems/ruby-1.9.3-p194@something/gems中。因此，'bundle list'会显示gem，但'gem list'不会。

有什么想法吗？我真的不想使用bundle来执行所有操作。

Bundler用于将gem与应用程序捆绑在一起。使用它来安装系统gems毫无意义。不幸的是，非Bundler gem系统没有直接安装基于git的gems的方法（我之前问过这个问题，请参见从git存储库直接安装gem是否可能？）。相反，您需要手动完成三个步骤：

Clone the gem repo (this is assuming a github repository, but it will work for a repository hosted anywhere, just substitute the right git repo location).
```
git clone git://github.com/user/gem.git
```
Go to the cloned gem repo directory and build the gem (this will also check for dependencies and warn you if the install failed because of a missing dependency -- in that case just install the dependencies and try again).
```
rake gem
```
Or if that doesn't work:
```
gem build gem.gemspec
```
This should have created a file with a name like pkg/gem-1.2.3.gem (sometimes it will build in the pkg directory like this, sometimes it will build in the gem repo root directory). You can now install it.
```
gem install pkg/gem-1.2.3.gem
```
