我在 django 上开发了一个项目多年，并将其部署在 heroku 上。
现在我的电脑崩溃了，我尝试让我正在运行的 django 项目从 heroku 运行在我的新笔记本电脑上的 pycharm 中。
-我从heroku克隆了我的项目 -安装了所有依赖项 -创建了新的venv -设置系统变量密钥等...
似乎我有多个问题...
尝试了所有方法并阅读了数小时和数天，但无法使其正常工作....
任何提示都会有用

仔细阅读以上内容。在 urls.py 中，通常会为视图函数分配路径。因此
angebot_views.generate_pdfangebot_viewsangebot.viewsgenerate_pdf确认该视图函数存在并且正确导入后，您可以进一步搜索。
既然您说您没有更改任何内容，只是复制了整个项目，我的下一个想法就是更改导入路径。 请记住，导入在某种程度上取决于流程的启动位置。您是否更改了 manage.py 文件的位置（因为这是“启动”项目的文件）？
错误不在依赖项内，而是与找不到视图函数有关。您必须找到它并在您的 angebot/urls.py 中正确导入和分配它
