When I tried to package a program with Nuitka, the generated exe file told me

"

Traceback (most recent call last):

AttributeError: type object 'type' has no attribute '_signature_'

", so I see the source code and found that this line was fine, because it imported the Shiboken2 package, and since which line of code would not go wrong at runtime, I suggested changing"type._signature_"to"

"

try:

    type._signature

except AttributeError:
    pass
