Ruby on rails 通过RVM安装的ruby不'；（诺默耶罗说）

我尝试过使rvm内爆，从头开始安装所有东西，奇怪的是，它一直工作到我重新启动shell（我使用zsh，但在bash上也发生了同样的情况）

控制台输出：

➜  ~backend_folder git:(master) ✗ which rails

/Users/shaioz/.rvm/gems/ruby-1.9.3-p429/bin/rails

➜  ~backend_folder git:(master) ✗ rails server

但奇怪的是，rvm没有安装在sudo用户上，而.rvm则安装在我用户的homedir上。 我在OSX 10.8.3上运行，我找到了答案。 在$PATH中，我让本地ruby先于rvm安装的ruby，但rails是rvm安装的与ruby版本相匹配的rails。 （不正确的$PATH是由于我的zshrc中有一个不必要的条目）

简而言之，如果你有类似的问题，试着

$ which ruby; which rails

---

看看它们是否是正确的版本。

rvm类型头-n 1的输出是什么？

rvm是一个外壳函数

Ok，这很好。也许可以试试

rvm需求

，看看它是否告诉您一些有用的信息？我想这也是一件好事。请显示

rvm配置get

$ which ruby; which rails
