错误：django.core.exceptions.ImproperlyConfigured：SECRET_KEY设置不能为空。在将应用程序部署到heroku时

标签： django heroku

我是一个初学者，尝试使用Heroku部署我的第一个Django项目，但现在在运行git push master heroku命令时遇到了空的SECRET_KEY问题： 经本地计算机检查，但我的应用程序在本地计算机上运行没有任何问题。 我已经检查了该网站上的其他解决方案，似乎都没有帮助我。

这是错误

` 一旦使用python secretes模块更改了密钥，就会发生相同的错误。 试图通过Decouple模块来访问环境变量，我遇到了一个错误，因此切换回Windows环境变量。
