Heroku 推送找不到 Django 3.2.8

Question

將我的 git 存儲庫推送到 heroku 時，它失敗並出現以下錯誤：

它使用與 django 3.2.8 兼容的 python 3.9.7。 奇怪的是，一切都很好，直到我按照本教程使用 Azure 托管靜態文件https://medium.com/@DawlysD/django-using-azure-blob-storage-to-handle-static-media-assets -from-scratch-90cbbc7d56be

從那時起，我不得不安裝 PostgreSQL 和 Visual Studio 才能讓 pg_config 文件正常工作。

編輯：這是requirements.txt：

Jinja2==2.11.2
Django-Heroku==0.3.1
Django-3.2.8
asgiref-3.4.1

Answer 1

-在版本說明符中無效。

格式為package-version所有依賴package-version需要更改為package==version 。

例如，改變

Django-3.2.8

到

Django==3.2.8

和

azure-storage-blob-12.9.0

到

azure-storage-blob==12.9.0
