打字

$ rails server

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

打字

localhost:3000

在浏览器上带来了一个损坏的网页，这意味着 rails 没有正常运行。

作为一个完整的初学者，我如何简单地逐步解决以下这些问题以使 Rails 运行？

【问题讨论】：

在终端中运行ruby -v 后的输出是什么？也是rails -v 的输出？

【解决方案1】：

编辑：先尝试运行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.
