Hi,  
I have the following problem:  
Under ParaView 5.11.2 (this installer: ParaView-5.11.2-Windows-Python3.9-msvc2017-AMD64.msi),  
pvpython fails with  
“ModuleNotFoundError: No module named ‘paraview’”  
on the line  
from paraview.simple import \*  
Is there something else I need to set up?  
Reading the documentation, I should not need any additional env variables when using pvpython  
With similar problems in this forum the recommendation was to use the binary install, but that is what I did.

Indeed, it should Just Work™. Does the `.zip` package work?

If not, I wonder if there’s something else interfering. Does `pvpython -dddd` have any useful info about the `paraview` module search?

pvPython -dddd or --dddd only returns this.  
unknown option --dddd  
usage: C:/Program Files/ParaView 5.11.2/bin\vtkpython [option] … [-c cmd | -m mod | file | -] [arg] …  
Try `python -h’ for more information.  
I will try out the zip package as well.

Hrm. How about setting `PYTHONDEBUG=4` in the environment first?

Do you have a `.local` folder ?
