Why can't Heroku install pywin32 ?

Answer 1

From its README :

This is the readme for the Python for Win32 (pywin32) extensions, which provides access to many of the Windows APIs from Python.

Heroku doesn't run on Windows, so there are no Windows APIs available. As a result pywin32 can't be installed.

You either have to host your application on Windows or remove the pywin32 dependency.

Answer 2

I have got same issue while deploying python script in to heroku . For me its working by removing below entries in requirements.txt

pypiwin32==223
pywin32==223

Below python version installed by default

Answer 3

只需从 requirements.txt 文件中删除它

Answer 4

Instead of removing on that dependency you can use pywin32==301; platform_system == "Windows" pywin32==301; platform_system == "Windows" to conditionally install it on on Windows
