我花了一整天的时间尝试从Rails 4x升级到5.2.1 . 我正在按照this指南进行升级，但我无法成功升级 .

Issue: "successfully"安装Rails 5之后使用： ruby 2.5.3p105 (2018-10-18 revision 65156) [x86_64-darwin17] 并且做了 rails -v 我得到：

rbenv: rails: command not found

The `rails' command exists in these Ruby versions:
  2.2.0

Things that I have tried: gem pristine different gems gem pristine --all this和路径一起玩但到目前为止没有运气 .

任何帮助将不胜感激

另外这里是我的宝石环境：

    您使用 rbenv 安装了 ruby ，现在您可以安装gems . 和 rails 是 ruby 的宝石 . 因此，首先要设置Ruby的全局版本，您应该在主目录中创建 .ruby-version 文件，并在其上编写已安装的ruby版本（ 2.5.3 ） .

    然后你应该运行 gem install rails 命令来安装rails .
