I get error "No module named 'pyproj._datadir'" after I made .py to .exe with pyinstaller [duplicate]

Question

My code works well when it's .py but when I make .exe file with pyinstaller, it shows ModuleNotFoundError.

I write this when I made .exe

pyinstaller -F MyCode.py

How can I solve this problem?

I've read some solutions from Issues with pyinstaller and pyproj so I was going to try to make and locate hook-pyproj.py at "hooks" folder in Pyinstaller. but hook-pyproj.py was already there with the same code.

After that, I installed "basemap" and tried to use pyproj from it. However it shows me the same error.

This is the error it showed me when I execute the .exe file. (I covered some information with *****)

This is my code.

from mpl_toolkits.basemap import pyproj as pyproj

I tried this at first.

import pyproj

but I get same " ModuleNotFoundError: No module named 'pyproj._datadir' " error.

Answer 1

It's a bit odd and I don't exactly understand why but I found a quick dirty fix. You can add this import

from pyproj import _datadir, datadir

to your existing one.

Answer 2

I noticed this pyproj import dll error error occurred on some Windows machines and not others.

Turned out to be a dependency on Visual C Runtime 2015+
