Change collections to collections.abc https://stackoverflow.com/questions/72032032/importerror-cannot-import-name-iterable-from-collections-in-python
Unfortunately, the version of future that this repo has pinned was affected by one of the breaking changes PSF pushed out with Python 3.9.
Without having to refactor any packaging or risk breaking anything else, here's a quick fix to make everything immediately "just work" if you're trying to run this on your system
import os, sys, re, pathlib
from tempfile import NamedTemporaryFile
def fix_pythonrubik_issue14(past):
assert sys.version_info < (4, )
p, = past.__path__
r = re.compile(r'^((?:from collections import )([\w, ]+))$', re.M)
for file in _recurse_files(pathlib.Path(p)):
body = file.read_text(errors='surrogateescape')
m = r.search(body)
if m:
newbody = r.sub(
lambda m: 'try:\n %s\nexcept ImportError:\n from collections.abc import %s' % m.groups(),
body)
_safe_overwrite(newbody, file)
def _recurse_files(d):
for dirpath, dirnames, filenames in os.walk(d):
for filename in filenames:
yield pathlib.Path(os.path.join(dirpath, filename))
def _safe_overwrite(src_content, dest):
# Reduce risk of corrupting system libraries
mode = 'w+b' if isinstance(src_content, bytes) else 'w+t'
with NamedTemporaryFile(mode, dir=dest.parent, delete=False) as f:
f_path = pathlib.Path(f.name)
f.write(src_content)
f.flush()
f_path.replace(dest) # This is as atomic as it gets, I think
