Steps to reproduce:

python3 -m venv myenv
cd myenv
. bin/activate
code .

Then in vscode I get asked if I would like to install pylint. I click on "yes".

The the error happens (this code was created/executed by vscode):

guettli@yoga15:~/projects/myenv$ source /home/guettli/projects/myenv/bin/activate
(myenv) guettli@yoga15:~/projects/myenv$ /home/guettli/projects/myenv/bin/python /home/guettli/.vscode/extensions/ms-python.python-2020.9.114305/pythonFiles/pyvsc-run-isolated.py pip install -U pylint --user
ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv.

Expected behaviour

Since the interpreter is in a virtualenv, it would make sense to avoid --user.

I can repro this.
