Hi,
I use Python 2.7. I have an Import Error: can not import name invalidate_caches. What should I do? 

from importlib import invalidate_caches

Upgrade to a version of python which has that module?

I have the same error in python3.5.

Mind showing the full traceback?  I'm on 3.6, so I can't replicate exactly what you're on, but it seems to work on my end.

Does it need to install special package?

Is this issue raised by you?

I get this with Python 2

Did you read post#2 by nilamo?

Also OP is now running python 3.5. (as per the screenshot he provided - Interpreter settings)

You didn't happen to name one of your files "importlib.py", did you?

The error is saying that the file is found, but that the function doesn't exist within it. Since importlib is part of the standard library, maybe the file's being shadowed somewhere?
