Deployment error with pywin32

Error : ```
ERROR: Could not find a version that satisfies the requirement pywin32>=223 (from pypiwin32) (from versions: none)

ERROR: No matching distribution found for pywin32>=223

requirements.txt file
pywin32==303; platform_system=="Windows"

How can i solve this?

You cannot install pywin32 in streamlit cloud.

i removed pywin from my requirements file and this is the new error

For whatever reason pip is trying to install pypiwin32, which seems to be a broken package. I cannot understand why this is happening, since requirements.txt should be empty by now. You may need to reboot or redeploy the application after making changes to requirements.txt.

I solved it already. First you just leave the requirements.txt empty. Then observe the errors during deploying the streamlit app, see what modules are missing. Then gradually add up the modules in the requirement file.

I have the same problem. Please can you help me?

  • cleanup your requirements file
  • do not use pip freeze to generate requirements file
  • remove any packages that are windows specific, streamlit cloud is linux debian based
  • only put packages into requirements file that you actually use in your application
  • do a reboot of the app on streamlit cloud
