ImportError: No module named 'tkinter' after pyInstaller
You should use hidden importpyinstaller eulersolver.py --hidden-import=tkinter -y
FINALLY WORKED FOR pyinstaller -F --hidden-import=tkinter --hidden-import=tkinter.filedialog prog.py Thanks a lot !!!
The problem is that pyinstaller won't see second level imports. So if you import module A, pyinstaller sees this. But any additional module that is imported in A will not be seen.
There is no need to change anything in your python scripts. You can directly add the missing imports to the spec file (prog.spec in your case).Just change the following line:
hiddenimports=[],to
hiddenimports=["tkinter"],After that run pyinstaller prog.spec to create the prog.exe.
