Cannot remove pip package with strange name

Hello, 

Could you please activate (https://virtualenv.pypa.io/en/latest/user_guide.html#activators) the same venv in a cmd/terminal and run :

pip freeze 

Will you see the same package name? 

I have tried to install it in my venv and it looks normal.  

-ycryptodome shows when I do `pip list`, but not when I freeze:

"WARNING: Could not generate requirement for distribution -ycryptodome 3.9.8 (e:\path\to\project\venv\lib\site-packages): Parse error at "'-ycrypto'": Expected W:(abcd...)"

-ycryptodome was not always in my list, I am afraid there is a more complicated repro for it to show up. My problem, however, is that I am stuck with it and can't remove it.

Please try to uninstall the package from the command line, running: 

pip uninstall -ycryptodome

or

pip uninstall pycryptodome

I am wondering what is the folder name under e:\path\to\project\venv\lib\site-packages  for the package? 

The case is very rare and specific, I cannot find ane information about similar cases. Are you able to reproduce it with a newly created venv? 

I did try the command line as I said in the initial report, unfortunately, it doesn't work. :(

I have the following folders in site-package, along with the proper pycryptodome folders.

I can't repro it in a different venv. I do believe the repro is complicated. I don't even think it would happen again. But what I would like now is to be able to remove this package, to be able to do a freeze.

Hello, 

it seems like the only way to get rid of the package is manually remove the folder. Please see the related ticket https://github.com/pypa/pip/issues/7763
