解决Gunicorn下Flask的TemplateNotFound错误
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:

回答:
你的模板位于[app root] / templates /中吗?
如果是这样,请检查以确保你的路径正确。将其作为处理首页的视图的第一行:
return app.root_path
如果这是你希望看到的-或者你正在使用蓝图或以某种方式更改默认Jinja Environment的其他方法-则要复杂一些。
奇怪的是,Jinja似乎没有jinja2.Environment.FileSystemLoader.get_search_path()方法。我以为它会有一个:(
