Rails服务器将无法运行
打字
$ rails server 在Mac上的终端产生这两个错误，我尝试通过卸载和再次安装ruby和rails进行故障排除并得到同样的错误。
打字
localhost:3000
在浏览器上带来一个破碎的网页，意味着rails无法正常运行。
作为一个完整的初学者，我如何逐步解决这些问题，以便逐步运行轨道？

编辑：尝试运行gem pristine --all第一。
尝试卸载并重新安装bundler：
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. Bundle complete! 33 Gemfile dependencies, 103 gems now installed.
