错误：django.core.exceptions.impropertlyconfigured:密钥设置不能为空。将应用程序部署到heroku时

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

命令时遇到了空密钥问题： 已在本地计算机上检查，但我的应用程序在本地计算机上运行，没有任何问题。 我在这个网站上查看了其他解决方案，它们似乎都没有帮助我

这是错误

提前感谢

您是否在heroku服务器设置中添加了环境变量？还要检查您是否为密钥提供了正确的拼写。刚才在你的设置文件中添加了“秘密密钥”，解决了我的问题。“secret_KEY”是环境变量中指定的变量。感谢You@NagArjun你能进一步解释一下你需要调整什么来解决这个问题吗？我在digital ocean上遇到了这样的构建错误。@ThomasByers刚刚在环境变量中添加了“SECRET_KEY”和其他必需变量。
