I have a kivy app running in a venv with different libraries like matplotlib. While following the official docs for packaging an app I got to the point where I can build my exe but when I run it I get a 'no module found'. Matplotlib however is correctly installed in the virtual env. Here is the error messsage:

Any help would be appreciated!

https://www.youtube.com/watch?v=NEko7jWYKiE&t=517s I suggestion Codemy about it.
Also when you show this error , are you tried again pip install matplotlib?
I used matplotlib to convert .exe and did work but i can't remember now. passed long months.

Try adding the missing library to the hiddenimports list in the spec file; or make sure it is imported in your python code. The error suggests that for some reason, pyinstaller is not seeing matplotlib, so it is not being pulled into the bundle.

Below is my “typical” windows spec file. The Collect section has a change – so the source files are not pulled into the bundle. Also notice the datas section is used to add the data directories to the bundle.

# -*- mode: python -*-

from kivy_deps import sdl2, glew

block_cipher = None
app_name = 'App Name Here'
win_icon = '../Images/my_icon.ico'

a = Analysis(['../main.py'],
             pathex=[],
             binaries=[],
             datas=[('../*.kv', '.'),
                    ('../Images/*.png', './Images')],
             hiddenimports=['win32timezone'],
             hookspath=[],


             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=

False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)


pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=

True,
          name=app_name,
          debug=False,

Thanks for the reply! So I tried the hiddenimports thing with matplotlib and now pyInstaller is complaining about a different library called librosa. Does not make sense because the PyInstaller doc states that you use --hidden-import for imports not visible in the code of the script(s) but the matplotlib import is visible in one of my .py files.

I put numpy, librosa and matplotlib into hidden_imports. Now I get a different error message. Seems to be a problem with the path. But the registry file is in the correct folder:
