部署 rails 应用程序时出现 nginx 错误消息
nginx error message while deploying rails app
我是第一次部署应用程序。
我正在使用最新版本在 rails 应用程序上开发 ruby，并遵循该教程：Deploy Ruby On Rails on Ubuntu 16.04 Xenial Xerus
一切正常，当使用 touch my_app_name/current/tmp/restart.txt 重新启动我的应用程序时，我收到附加的 nginx 错误
我尝试使用以下方法从 nginx 中获取错误日志：
sudo tail -n 20 /var/log/nginx/error.log
并得到以下信息：

@dstull 我不知道如何感谢你兄弟，你得到了 point.It 是我的 rails 应用程序的问题。我在开发阶段完成了我的应用程序，并且使用了一个主题（bootstrap 我购买的主题）。我的应用试图访问具有 nil 值的方法，因为还没有初始化任何东西。
