AWS Rails安装失败：activesupport需要Ruby版本> = 2.2.2 [英] AWS Rails install fails: activesupport requires Ruby version >= 2.2.2

问题描述

我正在aws上安装滑轨5。我已经安装了rvm和ruby。我安装的Ruby版本是2.3.1。我已经完成了捆绑安装。

I am installing rails 5 on aws. I have installed rvm and ruby. Ruby version I installed is 2.3.1. I have done bundle install.

现在，我正在尝试使用命令-'sudo gem install rails --version 5.0.0'

Now I am trying to install rails 5 by using command - 'sudo gem install rails --version 5.0.0'

但是我遇到错误

ERROR:  Error installing rails:
        activesupport requires Ruby version >= 2.2.2.

为什么显示需要的红宝石版本> = 2.2.2？我应该在这里做什么？

Why it is showing ruby version required >= 2.2.2 ? What should I do here?

推荐答案

由于您使用的是rvm，因此应为当前用户安装gem。这意味着没有 sudo 。

Since you are using rvm, you should install gems for the current user. That means without sudo.

gem install rails --version 5.0.0
