Issue description

There is a simple refactoring error which I've found in pipenv/utils/virtualenv.py.

I tried to install dependencies to an env I've just created as follows:

pipenv run pip install -r requirements.txt

Expected result

It should install the libraries or give a useful error.

Actual result

Steps to replicate

Provide the steps to replicate (which usually at least includes the commands and the Pipfile).

Try to install any library as follows:

python -m pipenv run pip install boto3

or simply type the following in a new directory:

pipenv shell

Pipefile:

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
boto3 = "*"

[dev-packages]

[requires]
python_version = "3.10"
