ruby-on-rails - 处理“宝石加载错误”时如何安装 Rails

问题描述

我试图让 Ruby on Rails 在我的笔记本电脑上工作，但一直没能。在某些时候，我接受了一些不好的建议并使用sudo并一直试图撤消该错误以及此后的相应问题。

截至目前，ruby -v节目

ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin19]

所以，我认为Ruby已安装。当我尝试运行gem install rails或任何其他 gem 命令gem install bundler时，我收到此错误

解决方案

我做了

sudo rm -rf ~/.rvm

因为我安装了 rvm 和 rbenv 并且有效
