ruby-on-rails – rails rbenv：rails：命令未找到

我最近从RVM转移到Rbenv,当试图执行rails时,我收到如下的错误

Pauls-Air:~ $rails
rbenv: rails: command not found

The `rails' command exists in these Ruby versions:
  2.1.2

解决方法

在ruby版本中通过命令行安装gem后,您必须按照文档 here和 here中所述执行rbenv rehash

例如：

$rbenv install 2.2.0
$gem install bundler
$rbenv rehash
$gem install rails
$rbenv rehash
