ModuleNotFoundError: No module named 'imagehash'?

[Rapid1898-code]

Hello - i have written a python-code which is using the imagehash module

from PIL import Image
import imagehash
import requests
img = "https://i.imgur.com/5bGzZi7.jpg"
resp = requests.get(img, stream=True)
ihashImg = imagehash.average_hash(Image.open(resp.raw)) 
print(ihashImg)

This works fine when i run the python-code in vscode.
But when i compile with pyinstaller (version 5.4.1) and try to create the windiows-exe with eg.

pyinstaller --onefile --hidden-import=imagehash test1.py
pyinstaller --onefile test1.py

With both variants i get this error when running the executeable:

Traceback (most recent call last):
  File "test1.py", line 2, in <module>
    import imagehash
ModuleNotFoundError: No module named 'imagehash'
[24964] Failed to execute script test1

Any ideas why this is not working?
Is it necessary to use some other parameters?

If a direct import from your entry-point script is not found at runtime, chances are very high that it cannot be found during the freezing process, typically because you have PyInstaller installed in a different python environment (virtual or base) than you usually use to run your code.

Hello - pyinstaller is also installed in the venv which i am using for program start.

What if you run pyinstaller via python -m PyInstaller instead of using the pyinstaller shim? The latter might (also) be installed in some other environment (which you can check with where pyinstaller)...

When i write this
python -m pyinstaller --onefile test2.py
he tells me for whatever reason
C:\Users\Polzi\Documents\DEV\.venv\test\Scripts\python.exe: No module named pyinstaller

But when i do pip list (within the activated venv) i get this:

pyinstaller               5.4.1
pyinstaller-hooks-contrib 2022.10

How is this possible?

When i do where pyinstaller i get:

C:\Users\Polzi\Documents\DEV\.venv\test\Scripts\pyinstaller.exe
C:\Users\Polzi\AppData\Local\Programs\Python\Python39\Scripts\pyinstaller.exe

PyInstaller the module name is case sensitive. You need to use python -m PyInstaller.
