Length of package more than 2147483647 bytes

Change:

struct.unpack('!8siiii64s', self.fPtr.read(self.PYINST21_COOKIE_SIZE))

To:

struct.unpack('!8sIIII64s', self.fPtr.read(self.PYINST21_COOKIE_SIZE))

Will solve this error:

And these place, change to unsign int

nameLen = struct.calcsize('!IIIIBc')

(entryPos, cmprsdDataSize, uncmprsdDataSize, cmprsFlag, typeCmprsData, name) =
struct.unpack(
'!IIIBc{0}s'.format(entrySize - nameLen),
self.fPtr.read(entrySize - 4))

Might be built with a modified pyinstaller.

[kitcheng]

nameLen = struct.calcsize('!IIIIBc')

(entryPos, cmprsdDataSize, uncmprsdDataSize, cmprsFlag, typeCmprsData, name) = struct.unpack( '!IIIBc{0}s'.format(entrySize - nameLen), self.fPtr.read(entrySize - 4))

As I wrote, change signed integer in the code to unsigned integer will solve this bug.
Search: struct.unpack('!8siiii64s', self.fPtr.read(self.PYINST21_COOKIE_SIZE))Replace: struct.unpack('!8sIIII64s', self.fPtr.read(self.PYINST21_COOKIE_SIZE))
iiii to IIII , signed integer to unsigned integer.

search and replace these code also: 
nameLen = struct.calcsize('!IIIIBc')(entryPos, cmprsdDataSize, uncmprsdDataSize, cmprsFlag, typeCmprsData, name) =
struct.unpack(
'!IIIBc{0}s'.format(entrySize - nameLen),
self.fPtr.read(entrySize - 4))
