从rvm切换到system ruby使我无法访问gems

今天我从rvm切换到使用SystemRuby，我不得不在我的项目目录中重新运行bundle，这并不奇怪。但这样做之后，我再也不能通过命令行访问gems了

例如：rspec规范即使在包中包含rspec的项目中也不再有效。当我检查rspec的位置时，它仍然在.rvm目录中：

$ gem which rspec
/Users/jeremysmith/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/gems/1.9.1/gems/rspec-2.6.0/lib/rspec.rb

我已经检查了$GEM_HOME，但它没有设置为任何值

更新：

我通过运行以下命令切换回系统ruby：

rvm use system

当我尝试的时候

bundle exec rspec spec

我得到了另一个即使安装了也找不到的宝石：

uninitialized constant Object::Rack (NameError)

问题是rubygems仍然安装在.rvm目录中。因此，我尝试删除rubygems，但我仍然将gem安装放在.rvm目录中，即使在我的bash文件中删除了所有对.rvm的引用

---

但我发现，当我告诉.rvm使用系统ruby时，我在/usr/bin中的系统ruby仍然有对.rvm的引用。所以我内爆了rvm，从源代码构建了ruby，现在一切都正常了。

您能详细介绍一下迁移到system ruby的步骤吗？另外-要从Bundler管理的gem运行二进制文件，您应该绑定exec。嗨，Brandon，我更新了我的帖子来回答您的问题。谢谢，Jeremy，还有一个问题：如果rvm调试不包含它，rvm调试和rvm信息的输出是什么？我注意到的第一件事是，您的rvm已经过时几个月了。试试看这是否有帮助。您的.bash_配置文件似乎正在加载RVM两次；这应该没有什么区别，但我会1删除多余的行，2确保剩余的行是.bash_配置文件中的最后一项。还有rvm reset，它可以重置rvm的选项，并使其忘记您可能希望尝试的默认选项。一旦切换到ruby系统，您在rvm rubies下安装的gems将无法在其他任何地方使用。这就是RVM的目的，拥有相互不影响的封闭环境。如果您想访问gems，您必须使用安装它们的Ruby，RVM不会在不同的Ruby之间共享gems。
