Python package certifi_win32 is missing after installed ArcGIS Pro 3.3

After installed ArcGIS Pro 3.3, Python package certifi_win32 is missing in C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages.

You will find that with the latest version many packages that were present at 3.1 and 3.2 are missing. This is because nested dependencies are not supporting the version ESRI validated for release so they are not accessible.

@DEWright_CA

We need to use certifi_win32. What/how should we do?

Thanks.

I updated ArcGIS Pro 3.3 to 3.3.1, but Python package certifi_win32 is still missing in C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages.

I also have ArcGIS Pro 3.3.1 and need the certifi_win32 python package for a MOOC session. I have the certifi_win32 folder with only a _pycache_ folder containing some .pyc files.

I had the same issue and was able to fix it following the steps below:

1) Rename Python folder by navigating to C:\Program Files\ArcGIS\Pro\bin\Python and rename the Python folder to Python_old

2) Repair the ArcGIS Pro installation.
To repair the software, open the Start menu, search for Apps & features, and find ArcGIS Pro.
Click on ArcGIS Pro, select Modify, and then choose Repair. Follow the prompts to complete the repair.

This just worked for me in my development environment. We're planning on upgrading our enterprise geodatabases and portal to from 11.1 to 11.3. When testing python scripts after the Pro 3.3.5 upgrade, I came across this error when trying to import server from the arcgis.gis module. Error: certifi_win32.wincerts.verify_combined_pem() ^^ AttributeError: module 'certifi_win32' has no attribute 'wincerts'. We use this to start and stop services on standalone arcgis servers. I'm wondering if I should've removed the C:\Program Files\ArcGIS\Pro directory after uninstalling the previous version of Pro.
