Rails服务器将无法运行

Question

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,以便让轨道运行？

编辑:gem pristine --all首先尝试运行.

尝试卸载并重新安装bundler:

gem uninstall bundler 然后 gem install bundler

然后跑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.
