问题描述
我遇到了RVM的问题。一般来说，我使用项目特定的宝石;然而，最近当我在@global gemset中安装一个gem时，当我在一个特定的项目中工作时它不可用。这里是我试图安装 hpricot gem的一个例子。在安装gem并启动一个新shell后，这是正确的。
$ rvm使用ruby-1.9.2
使用/home/bshaver/.rvm/gems/ruby-1.9.2-p180
$宝石名单
***本地GEMS ***
bundler（1.0.12）
hpricot（0.8.4）
rake（0.8.7）
$ rvm use ruby-1.9.2@myproject-gems
在gemset中使用/home/bshaver/.rvm/gems/ruby-1.9.2-p180 myproject-gems
$ gem list | grep hpricot
$ rvm info

为什么 hpricot 在项目gemset中不可用？我确实也遇到了与 bundler 相同的问题，但最终再次将其安装在gemset中。
谢谢..
解决方案
这里的问题是，第一次安装hpricot gem时，我没有使用 @global gemset。
解释器的默认gemset与该解释器的 @global gemset有所不同。
所以你可以通过
$ rvm来实现所需的结果use ruby-1.9.2@global
使用/home/bshaver/.rvm/gems/ruby-1.9.2-p180和gemset global
$ gem install validation_refelection
获取：validation_reflection-1.0.0.gem（100％ ）
已成功安装validation_reflection-1.0.0
1已安装gem
为validation_reflection-1.0.0安装ri文档...
为validation_reflection-1.0.0安装RDoc文档.. 。
$ rvm use ruby-1.9.2@myproject-gems
使用/home/bshaver/.rvm/gems/ruby-1.9.2-p180和gemset myproject-gems
$ gem list | grep validation_reflection
validation_reflection（1.0.0）
该项目可以使用gem希望。
I'm having an issue with RVM. In general I use project specific gemsets; however, recently when I install a gem into the @global gemset, it is not available when I'm working in a particular project. Here is an example where I was trying to install the hpricot gem. This is right after installing the gem and starting a fresh shell.
$ rvm use ruby-1.9.2
Using /home/bshaver/.rvm/gems/ruby-1.9.2-p180
$ gem list

$ gem list | grep hpricot
$ rvm info

Any ideas why hpricot would not be available inside of the project gemset? I did have the same issue with bundler as well, but ended up installing it again in the gemset.
Thanks..
解决方案
The problem here is that I wasn't using the @global gemset when installing hpricot gem the first time.
There is a difference between the interpreter's default gemset and the @global gemset for that interpreter.
So you can achieve the desired result by
$ rvm use ruby-1.9.2@global
Using /home/bshaver/.rvm/gems/ruby-1.9.2-p180 with gemset global
$ gem install validation_refelection
Fetching: validation_reflection-1.0.0.gem (100%)
Successfully installed validation_reflection-1.0.0
1 gem installed
Installing ri documentation for validation_reflection-1.0.0...
Installing RDoc documentation for validation_reflection-1.0.0...
$ rvm use ruby-1.9.2@myproject-gems
Using /home/bshaver/.rvm/gems/ruby-1.9.2-p180 with gemset myproject-gems
$ gem list | grep validation_reflection
validation_reflection (1.0.0)
And the gem is available to the project as desired.
