  • Issues in using PyInstaller with Tkinter

TKinter is used in easygui for creating GUIs. Somehow when installing PyInstaller, the system will use the python in Panda package if it is installed on the system, which may not have all the required modules. Therefore, a quick solution is to first remove all Panda installations on the system, and then install the PyInstaller package again. There is sometimes also a warning saying that:

WARNING: file already exists but should not: C:\Users\username\AppData\Local\Temp\_MEI86402\Include\pyconfig.h

This is caused by repetitive importing of the pyconfig.h in the current release of PyInstaller. To fix it, one can manually "patch" the problem by adding the following lines into the *.spec file (generated after using python makespec.py <yourfile.py>):

for d in a.datas:
    if 'pyconfig' in d[0]: 
        a.datas.remove(d)
        break

Not as convenient as one would hope, but it works (see similar issue here).
