Using pipenv installed under pipx gives "Pipenv found itself running within a virtual environment"

[pfmoore]

Issue description

I have pipenv installed using pipx, which means that it's installed in a venv. This is deliberate, as I do not want to install pipenv and all its dependencies in my system Python, and there's no other recommended approach in the pipenv docs for how to install pipenv standalone.

When I run pipenv, I get the error "Pipenv found itself running within a virtual environment". However, I see no evidence that pipenv didn't create a virtual environment, nor do I see any problems resulting from running pipenv in this way.

Note There are a number of duplicates for this issue, but they all refer to MacOS and (as far as I can see) the Homebrew version of Python. This report is for Windows using the normal python.org installer. Please do not close this as a duplicate without ensuring that whichever issue is being treated as the "master" is updated to note that it is not a MacOS specific problem.

Expected result

• Not to get a "Courtesy Notice" that is neither helpful nor, as far as I can see, accurate.
• Not to have to set environment variables to use pipenv normally.

Actual result

When possible, provide the verbose output (--verbose), especially for locking and dependencies resolving issues.

Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning.

Note that sys.executable is in a pipenv-created directory, so it apparently did create one...

Can you please have a try against the master branch to see if the issue is gone? Will cut a new release shortly if so.

[pfmoore]

No, it still happens in master, I'm afraid.

[pfmoore]

Just to clarify here - I do have pipenv running in a virtualenv. So the initial part of the "courtesy notice" is correct. What is not correct, as far as I can see, is the statement that it will "automatically use that environment". It doesn't, and furthermore I don't want it to. I want to be able to install pipenv in an isolated environment, not in my system (or user) site-packages, and have it work.

In practice, the issue here is that the message and the behaviour don't match - and what I want is the current behaviour, but not the (incorrect) message.

I'm not clear why anyone would want pipenv to automatically use an existing virtual environment. And in practice, nothing I've tried has been able to provoke it to do so...

[pfmoore]

Update: Looking through the source, I see that one difference which may be relevant here is that I run pipenv using my virtualenv Python, but I do not activate that virtualenv. So sys.executable is in a virtualenv, and is_in_virtualenv will therefore be true, but the virtualenv is not on PATH, and VIRTUAL_ENV is not set (so Project.virtualenv_location won't see the environment pipenv is installed in).
