由于手动将其设置为 python 后构建包不兼容，我正在努力在 Heroku 上部署我的 Django 项目（Django 3.1）

Question

我的第一次尝试是在不手动设置默认语言的情况下直接推送到 heroku：

(myenv) ➜  quotatev3 git:(main) heroku create quotatev3                           
 ›   Warning: heroku update available from 7.56.1 to 7.59.0.

remote: 
To https://git.heroku.com/quotatev3.git
 ! [remote rejected] main -> main (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/quotatev3.git'

因此，在手动设置后，我收到一条错误消息，提示我的应用与 build-pack 不兼容。

 (myenv) ➜  quotatev3 git:(main) heroku create quotatev3 --buildpack heroku/python
     ›   Warning: heroku update available from 7.56.1 to 7.59.0.

我不确定这是因为我的 python 版本已经过时（使用 python 3.9.5）还是其他地方有错误。谢谢你的帮助！！
