Using virtualenv in VSCode gives ImportError: cannot import name 'appdirs' but normal terminal does not

Question

When using virtualenv in VSCode integrated terminal I get the following error when trying to use pip or pip3

Traceback (most recent call last):
  File "/home/me/repo/py-hello/venv/bin/pip3", line 5, in <module>
    from pip._internal.cli.main import main
  File "/usr/lib/python3/dist-packages/pip/_internal/cli/main.py", line 10, in <module>

    from pip._internal.utils import appdirs
  File "/usr/lib/python3/dist-packages/pip/_internal/utils/appdirs.py", line 13, in <module>
    from pip._vendor import appdirs as _appdirs
ImportError: cannot import name 'appdirs' from 'pip._vendor' (/usr/lib/python3/dist-packages/pip/_vendor/__init__.py)

However, this isn't the case when using a regular terminal. I can run pip fine.

I found a few mentions in other posts here and here but neither are helping me.
