ruby-on-rails - rails rbenv : rails: command not found

Question

我最近从 RVM 转移到 Rbenv 并且在尝试执行 rails 时出现如下错误

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

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

Answer 1

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

例如:

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