我在RVM上遇到问题。通常，我使用项目特定的宝石集；但是，最近，当我在@global gemset中安装gem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。这是在安装gem并启动新外壳之后的。
$ rvm use ruby-1.9.2

有什么想法为什么在项目gemset中无法使用hpricot？捆绑器也确实存在相同的问题，但最终还是将其再次安装在gemset中。
谢谢..
最佳答案
这里的问题是我第一次安装hpricot gem时没有使用@global gemset。
解释程序的默认gemset与该解释程序的@global gemset之间有区别。
因此，您可以通过以下方式获得所需的结果
$ rvm use ruby-1.9.2@global
Using /home/bshaver/.rvm/gems/ruby-1.9.2-p180 with gemset global
$ gem install validation_refelection

宝石可根据需要用于项目。
