[英]Python Flask (deployed on Heroku): ImportError: cannot import name 'secure_filename' from 'werkzeug' when deploying on Heroku
问题描述
When deploying a flask application on heroku im getting the error above.
在 heroku 上部署 flask 应用程序时，我收到上述错误。 The problem on heroku is that it installs dependencies and Iam not able to overwrite them then, or? heroku 的问题是它安装了依赖项，然后我无法覆盖它们，或者？ On my local server i just went to flask_uploads.py and change the imports to:在我的本地服务器上，我只是去了 flask_uploads.py 并将导入更改为：
from werkzeug.utils import secure_filename
from werkzeug.datastructures import FileStorage
and this works fine.这很好用。
but when deploying the flask app to heroku, how can I change the the content of flask_uploads.py after it had been installed?但是在将 flask 应用程序部署到 heroku 时，安装后如何更改 flask_uploads.py 的内容？

flask-uploads is no longer properly maintained and has not released a fix to the updated Werkzeug API change, thus you see this error. flask-uploads不再正确维护，并且尚未发布对更新的 Werkzeug API 更改的修复，因此您会看到此错误。
Just swap flask-uploads with flask-reuoloaded in your dependency list, eg requirements.txt or similar.只需在依赖项列表中将flask-uploads与flask-reuoloaded交换，例如 requirements.txt 或类似文件。 You don't have to change your imports!你不必改变你的进口！
