Debug raising error when running as packaged app by pyinstaller

[zlt999]

I run the packaged app by pyinstaller on windows platform, and get error raised as below:

AttributeError: module 'resource' has no attribute 'getpagesize'
[PYI-26572:ERROR] Failed to execute script 'main' due to unhandled exception!

Still not sure where this resouce.py come from. I use dir() and get output as below:

['__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__']

This resource.py seems to be empty.

After all, I changed the source code in elffile.py and the problem is gone.

IIRC, resource is a built-in library in CPython.

@eliben This looks inoffensive enough. PAGESIZE, strictly speaking, is not even particularly necessary - it's only used for reading chunks to be decompressed, a hard coded buffer size would do just as well.

@sevaa agreed, would you like to send a quick PR to remove all that PAGESIZE mess? I suppose something like a 4 KiB buffer size would do
