答案 0 :(得分：0)
这里有三个独立且未实现的问题：
heroku open。无论哪种方式，它只是一个快捷方式，您可以直接在浏览器中打开您的heroku应用程序。gunicorn中安装INSTALLED_APPS，添加它并重试。 （这也在您提到的链接中明确提到。）SECRET_KEY 答案 1 :(得分：0)
您的requirements.txt也必须有一条枪支线。
pip install gunicorn
pip freeze > requirements.txt
git add requirements.txt
git commit -m "updated requirements"
git push heroku master
再试一次：
heroku open
我猜你也错过了requirements.txt中的其他项目，因为你遇到了这个错误，但这有助于你克服没有被发现的枪支。
