每次关闭端子导轨时，默认值会从3.0.3恢复为2.3.5吗? [英] Every time I close terminal rails defaults back to 2.3.5 from 3.0.3?

问题描述

我正在通过示例教程进行学习.

I'm going through the rails by example tutorial.

似乎每次我关闭终端导轨时，默认值都回到2.3.5& ;;每次打开终端时，我都必须经历安装3.0.3的过程吗?

Its seems that every time I close terminal rails defaults back to 2.3.5 & I have to go through the process of installing 3.0.3 every time I open the terminal?

我使用以下命令安装了rails:$ [sudo] gem install rails --version 3.0.3

I installed rails using: $ [sudo] gem install rails --version 3.0.3

有人遇到过类似的问题吗?我试着在谷歌上搜索并搜索堆栈无济于事.

Has anyone experienced a similar issue? I've tried googling around and searching stack to no avail.

推荐答案

尝试卸载rails gem:

Try uninstalling the rails gem:

gem uninstall rails

如果系统提示您选择版本，请选择2.3.5并保持3.0.3版本不变.

If you are prompted to select a version, select 2.3.5 and leave the 3.0.3 version intact.

PS:您正在使用 RVM 吗?如果没有，我会极力推荐.

P.S: Are you using RVM? If not, I would highly recommend it.
