Capistrano部署独角兽错误未初始化常量RAILS_ENV（NameError）

Question

我刚刚成功地将我的RoR应用程序部署到使用橡胶& Capistrano的AWS。但是，当我导航到页面时，它显示默认的nginx页面。显然，我在设置阶段错过了一些东西，将nginx/unicorn指向正确的目录来为我的应用程序提供服务。

当我运行tail -f log/unicorn.stderr.log我看到以下内容：

E, [2015-12-07T14:23:41.253757 #3808] ERROR -- : reaped #<Process::Status: pid 24405 exit 1> worker=0

/ebs/microposts2-production/shared/bundle/ruby/2.0.0/bin/unicorn_rails:23:in `<main>' 

我假设，因为环境被追加到我的应用程序名称Rubber.env存在，但是这个错误让我认为并非如此。哎呀，我甚至不确定这个问题甚至适用于nginx默认页面问题。有人可以分享我做错了什么，或错过了吗？

你需要清除默认的nginx虚拟主机通常在/etc/nginx/sites-enabled/default，只需删除该文件，然后你应该很好去。
