Question

我试图破坏rvm并从头开始安装所有内容，奇怪的是它一直有效，直到我重新启动我的shell（我使用zsh，但在bash上也是如此）。

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

（这也发生在我使用irb时，我至少有2 GB的RAM可用）当我尝试'rvm get'时，我明白了：

cat: /Users/shaioz/.rvm/help/get: No such file or directory
Could not update RVM, get some help at #rvm IRC channel at freenode servers.

但奇怪的是，没有在sudo用户上安装rvm，而.rvm位于我用户的homedir上。我正在运行OSX 10.8.3

Answer 1

我明白了。在$ PATH中，我将本地ruby先于rvm安装的ruby，但是rails是由rvm安装的以匹配ruby版本的。（不正确的$ PATH是由于我的zshrc中不需要的条目）

简而言之，如果您遇到类似的问题，请尝试

$ which ruby; which rails

并查看它们是否是正确的版本。

通过RVM安装的ruby不会运行（NoMemoryError说）
