Flask running on Python3.6 can't find htmlentitydefs?

Question

I'm running Python3.6 intel anaconda distribution on a disconnected environment.

I installed the following wheels:

Click-7.0-py2.py3-none-any.whl
Flask-1.1.1-py2.py3-none-any.whl
itsdangerous-1.1.0-py2.py3-none-any.whl
Jinja2-2.10.1-py2.py3-none-any.whl
Werkzeug-0.15.6-py2.py3-none-any.whl

pip says all of my requirements are installed, but when I do an import flask, I get this error:

$python

>>> import flask

    from html.entities import name2codepoint
ModuleNotFoundError: No module named 'html.entities'

During handling of the above exception, another exception occurred:

  File "/intelpython3_2019.2/lib/python3.6/site-packages/flask/__init__.py", line 16, in <module>

    from htmlentitydefs import name2codepoint
ModuleNotFoundError: No module named 'htmlentitydefs'
>>>

So this makes no sense, because htmlentitydefs is a python2 thing, and I'm running on python3, and I installed everything from python2/python3 wheels.

What do I need to install to fix this?

hmm interesting, werkzeug [loads](https://github.com/pallets/werkzeug/blob/master/examples/plnt/utils.py#L54-L57) the python 3 version of name2codepoint first, then falls back to the python 2 version. I wonder if the python 3 version is fully installed. — IronMan, Sep 17 '19 at 17:49

If there is a directory called html in the current directory, python fails when it attempts to load the html module. I did a rmdir html in the current directory and this problem went away.

How did you even find that :D – Robin De Schepper Mar 12 '20 at 19:42
It took effort. This question is *not* a duplicate. – vy32 Mar 12 '20 at 20:34
