Spacy — ImportError: preshed.maps does not export expected C function map_clear

问题

I am trying to import spacy in vain.

>>> import spacy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\Alienware\Anaconda3\envs\tf2\lib\site-packages\spacy\__init__.py", line 12, in <module>
    from . import pipeline

    from .pipes import Tagger, DependencyParser, EntityRecognizer, EntityLinker
  File "pipes.pyx", line 24, in init spacy.pipeline.pipes
  File "C:\Users\Alienware\Anaconda3\envs\tf2\lib\site-packages\spacy\pipeline\functions.py", line 5, in <module>
    from ..matcher import Matcher
  File "C:\Users\Alienware\Anaconda3\envs\tf2\lib\site-packages\spacy\matcher\__init__.py", line 5, in <module>
    from .phrasematcher import PhraseMatcher
  File "phrasematcher.pyx", line 1, in init spacy.matcher.phrasematcher
ImportError: preshed.maps does not export expected C function map_clear

I updated conda and then run update conda all. I removed the previous version of python and installed the newest one (3.8). I uninstalled spacy and reinstalled it. Nothing worked.

The last time I worked with spacy was 3 weeks ago and I did not face any problem. All of a sudden this exception erupted out of nowhere.

What is your understanding of the situation? Any ideas on how to debug the problem or remedy the failure?
