Problem in importing Counter. How can I fix it?

$ nasty search --query "climate"

The problem seems to be with importing typing.Counter. Can you run a new Python script just with the following?

from typing import Counter

Also, what Python version are you running?

• Can you give me the result of python -VV from a command line and

• the output of following running inside Python?

  import sys
  print(sys.version_info)

For me I get Python 3.6.9 (default, Nov 23 2019, 06:41:34) and sys.version_info(major=3, minor=6, micro=9, releaselevel='final', serial=0), respectively. With that importing typing.Counter should not be a problem.

I also get the same thing you got for sys version : sys.version_info(major=3,minor=6, micro=0, releaselevel='final', serial=0) and $ python -VV

Python 3.6.0 (v3.6.0:41df79263a11, Dec 23 2016, 08:06:12) [MSC v.1900 64 bit (AMD64)]

The script for typing.Counter runs just fine.

Hm, according to the documentation typing.Counter should only be available starting from Python 3.6.1.

Could you try upgrading your Python installation to at least that?

Still, I am somewhat surprised that the plain from typing import Counter works for you because when starting with a plain Python 3.6.0 installation it fails for me, e.g.:

$ docker run --rm -it python:3.6.0 python -c "from typing import Counter"

The upgrade to a higher version did the job.

Thank you
