Django 部署到Heroku时出错

我在Heroku上部署了一个Django项目。项目正在我的本地服务器上运行。但是在部署之后，我看到以下错误：“内部服务器错误”

Heroku的日志堆栈如下所示：

我哪里出错了？

似乎postgresql没有为您的实例正确配置：

“没有名为psycopg2.extensions的模块”

。通读Heroku的devcenter，其中详细介绍了如何为您的实例启用postgresql。它甚至包括django的特定步骤。

请粘贴完整的回溯。@Burnkhalid:将问题本身编辑为包含完整的堆栈。谢谢，我还有一个问题。当我第一次部署任何应用程序时，我不知道如何将本地目录结构的路径更改为Heroku服务器的路径。例如，我的setting.py中的模板_DIRS是“/home/xys/abcd”，现在在部署之前，我需要将其更改为Heroku服务器的路径。你能给我提供一些链接或指导我怎么做吗？从这个开始，在heroku上给django。谢谢Burhan，我会跟进的
