当我执行"捆绑安装"；发生这种情况：您的Ruby版本是2.3.3，但您的Gemfile指定了2.7.1我能做什么？我正在使用我的电脑、Git Bash和Visual Studio
此处错误
我的Gemfile:

我没有做任何改变
您需要在机器上安装ruby 2.7.1版本才能继续。
或者，您可以更改Gemfile中指定的"ruby版本"以匹配现有版本(2.3.3(。这是一个相当大的更改，项目可能无法使用这样的旧版本。
您正在使用ruby版本管理器吗？这个Gemfile是从哪里来的？
如果这是因为您使用rails new启动了一个新的rails项目，那么您很可能希望使用比2.3.3更现代的ruby版本运行，这意味着(正如我在第一行中所说(，您需要升级系统的默认ruby。
我认为您可以遵循本教程https://medium.com/ruby-on-rails-web-application-development/how-to-install-rubyonrails-on-windows-7-8-10-complete-tutorial-2017-fc95720ee059，当你得到ruby 2.7.1时，你可以毫无问题地开始。
