rails rbenv:rails:找不到命令 [英] rails rbenv: rails: command not found

问题描述

我最近从 RVM 转移到了 Rbenv，在尝试执行 rails 时，我收到如下错误

I have recently moved from RVM to Rbenv and when attempting to execute rails I am getting an error like the one below

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

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

推荐答案

在 ruby​​ 版本中通过命令行安装 gem 后，您必须按照文档 rbenv rehash="https://github.com/sstephenson/rbenv#rbenv-rehash" rel="noreferrer">这里 和 这里

After installing a gem via the command line in a ruby version you have to execute rbenv rehash as described in the docs here and here

例如:

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