The following code in py_compile.compile fails (tested on 3.6.6 and 3.7.3) with tracebacks that end like the one shown at the bottom. There's an AttributeError about importlib.utils. """ if cfile is None: if optimize >= 0: optimization = optimize if optimize >= 1 else '' cfile = importlib.util.cache_from_source(file, optimization=optimization) else: cfile = importlib.util.cache_from_source(file) """ Sample tail end of traceback: """ File "/Users/jens/src/.eggs/Chameleon-3.6-py3.7.egg/chameleon/template.py", line 243, in _cook cooked = self.loader.build(source, filename) File "/Users/jens/src/.eggs/Chameleon-3.6-py3.7.egg/chameleon/loader.py", line 177, in build py_compile.compile(name) File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/py_compile.py", line 130, in compile cfile = importlib.util.cache_from_source(file) AttributeError: module 'importlib' has no attribute 'util' """

Can you please add a simplified script to reproduce this and possibly without any external dependencies? Looking at the traceback it seems to come from the project chameleon at https://github.com/malthe/chameleon/blob/983877e628a75f42c473cb2ea2350fb0727eb85b9/src/chameleon/loader.py#L177 . The file seems standalone without some helper functions from utils file.

Thank you for the prompt reply. It turns out this is not a bug in py_compile. Other code we use imports importlib.util briefly for a quick check at module level and then deletes it, also at module scope. Removing the deletion fixes the issue. Thanks again and apologies!

No problem, closing the issue.
