我有一个Flask应用程序，正在尝试使用Gunicorn和nginx进行部署。但是，尽管它在本地运行良好，但是当我在远程服务器上使用Gunicorn运行时，它会引发TemplateNotFound错误。

我不确定如何开始调试它，更不用说它为什么会失败了……希望对前者有所帮助，即使不是后者。我以为这可能是权限问题，所以将模板文件夹更改为777 …没有运气。这是所有相关的细节：

安装脚本
从纯粹的Ubuntu 10.04安装开始，我运行它来设置服务器并插入我的代码：https : //github.com/total-impact/total-impact-deploy/blob/master/deploy.sh。然后，我将此nginx配置文件放在/ etc / nginx / sites-available / total-impact中：

server {
    location / {
        proxy_pass http://127.0.0.1:8000;
    }
}

最后，我浏览应用程序目录并运行gunicorn web:app，然后点击服务器的IP地址。这将在浏览器中生成500，并在命令行上输出：
