使用Rails部署时，localhost:3000链接显示空白页

我以前一直在使用Rails应用程序，服务器工作正常. 我关闭它并制作了一个新的 https://bitbucket.org/ScarletMcLearn/sample_app

I've been working on a rails app previously, the server worked fine. I closed it and made a new one https://bitbucket.org/ScarletMcLearn/sample_app

现在启动服务器时， http://localhost:3000 ，

and now when I started the server, the http://localhost:3000, http://localhost:3000/static_pages/home, and anything else remains blank.

我已经尝试使用Google搜索并阅读了一些Stackoverflow上的其他帖子，但是这些帖子对我没有帮助.我正在使用Mac-如果有帮助.

I've tried Googling and reading some other Stackoverflow posts, but they aren't working for me. I'm using a Mac - if it helps.

真的希望您能在这里为我提供帮助，因为我是Rails的新手，因此感谢您提供简单的说明.所有文件都在Bitbucket链接中.

Really hope you can help me out here, I'm new in Rails, hence simple instructions appreciated. All files are in the Bitbucket link.

感谢您的阅读. :D

Thanks for the read. :D
