Django Web应用程序Heroku Deployement :没有为decouple==0.0.7找到匹配的发行版

Question

我正在部署一个在Heroku上用Django制作的web应用程序。我遵循一个教程，在没有来自用户的任何CSS /图像输入的情况下，导师已经做了一个w/s。但我的应用程序有很多风格和配置图等，需要ImageField在模型中。

IMP ->我为Django 2.2做了一个项目，但是django 3已经发布了，所以我正在使用它。

请帮帮我.

我已经完成了以下步骤：

1. 安装Anaconda
2. 制作虚拟环境并激活它。
3. 已安装的pip
4. 已安装的依赖项
5. pip冻结> requirements.txt
6. 吉特加。& git推送-am“文本”
7. git推heroku大师

Answer 1

您将希望在项目根目录添加一个包含内容的runtime.txt文件:Python3.7.2

然后再推。

Answer 2

您使用Python3.6，decouple 需要 Python 3.7+。
