rubygems - RVM - 无法使用 @global gemset 中的 gem

Question

我的 RVM 遇到问题。一般来说，我使用项目特定的 gem 集；但是，最近当我将 gem 安装到 @global gemset 中时，当我在特定项目中工作时它不可用。这是我尝试安装 hpricot gem 的示例。这是安装 gem 并启动新 shell 后的情况。

$ rvm use ruby-1.9.2
Using /home/bshaver/.rvm/gems/ruby-1.9.2-p180

$ gem list

*** LOCAL GEMS ***

bundler (1.0.12)
hpricot (0.8.4)
rake (0.8.7)

$ 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 hpricot

$ rvm info

有什么想法为什么 hpricot 在项目 gemset 中不可用吗？我在 bundler 上也遇到了同样的问题，但最终还是在 gemset 中再次安装了它。

谢谢..

Answer 1

这里的问题是我第一次安装 hpricot gem 时没有使用 @global gemset。

解释器的默认 gemset 和该解释器的 @global gemset 之间存在差异。

这样你就可以达到想要的结果

$ 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...

$ 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)

并且该 gem 可根据需要提供给项目。
