Question

我在aws上安装rails 5。我已经安装了rvm和ruby。我安装的Ruby版本是2.3.1。我已完成捆绑安装。

现在我尝试使用命令安装rails 5 - 'sudo gem install rails --version 5.0.0'

但我收到错误

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

rvm list

=* ruby-2.3.1 [ x86_64 ]

完成登录运行命令 - 'sudo gem install rails --version 5.0.0'

为什么显示所需的ruby版本＆gt; = 2.2.2？我该怎么办？

Answer 1

由于您使用的是rvm，因此您应该为当前用户安装gem。这意味着没有 sudo。

gem install rails --version 5.0.0

AWS Rails安装失败：activesupport需要Ruby版本＆gt; = 2.2.2
