Can't run QT based GUI application bundled by pyinstaller, the console output shows it is due to an import error:
ImportError: unable to find Qt5Core.dll on PATH
Originally, the pyqt5/pyqt and pyinstaller is from condo. I've tried to reinstall pyqt5 and pyinstaller from pypi, but it does not solve the problem.
I checked the pyinstaller dist dir, it contains all needed dlls. When I am in conda env(Start a conda console, then run the bundled application in the console), the bundled application runs properly. I checked the loaded dlls, all of them are in the dist dir or system default dirs.
I'm on windows 10 x64 [Ver 10.0.18362.175], Python version is 3.7.3 from miniconda.

As detailed in the question, when startup the bundled application in the conda console, it runs properly, all the loaded DLLs, exported by ProcessExplorer, are in the dist dir which was created by pyinstaller. So the problem is that the path, containing pyqt DLLs, is not in the system's PATH environment. Maybe this is a bug of pyinstaller. The Solution is add the program path to system PATH env manually.
Here is the code snip i am using:
# Fix qt import error
# Include this file before import PyQt5
import os
import sys
import logging
def _append_run_path():
if getattr(sys, 'frozen', False):
pathlist = []
# If the application is run as a bundle, the pyInstaller bootloader
# extends the sys module by a flag frozen=True and sets the app
# path into variable _MEIPASS'.
pathlist.append(sys._MEIPASS)
# the application exe path
_main_app_path = os.path.dirname(sys.executable)
pathlist.append(_main_app_path)
# append to system path enviroment
os.environ["PATH"] += os.pathsep + os.pathsep.join(pathlist)
logging.error("current PATH: %s", os.environ['PATH'])
_append_run_path()
Assuming you don't absolutely need PyQt5 version 5.13.0, the easiest fix is to simply downgrade PyQt5 to version 5.12.2 using:
pip install pyqt5==5.12.2
and your executable will work as expected.
