python shutil.copytree - ignore permissions

Question

Python's shutil.copytree is not very flexible; what is the simplest way to add support for ignoring permissions while copying in copytree (without having to re-write its implementation)?

Otherwise, copytree fails like this:

(…)”[Errno 45] Operation not supported: ‘/path/foo/bar’”

Answer 1

Not thread-safe (or advisable in general) but OK for a throwaway script:

import shutil

_orig_copystat = shutil.copystat
shutil.copystat = lambda x, y: x

shutil.copytree(src, dst)

shutil.copystat = _orig_copystat
