Rails服务器不会运行

Question

正在打字

$ rails server

在 mac 上的终端中产生了这两个错误，我尝试通过卸载并再次安装 ruby & rails 进行故障排除并得到同样的错误。

正在打字

localhost:3000

在浏览器上带来了一个损坏的网页，这意味着 rails 没有运行正确。

作为一个完全的初学者，我如何简单地逐步解决下面这些问题，使rails达到运行？

编辑：首先尝试运行ning gem pristine --all。

尝试卸载并重新安装捆绑程序：

gem uninstall bundler 然后 gem install bundler

然后运行bundle install。

这将安装您应该在 Gemfile 中指定的所有 gem，以及所有扩展。

例如Bundle complete! 33 Gemfile dependencies, 103 gems now installed.
