pipenv requires python 3.7 but installed version is 3.8 and won't install

Question

I know a little of Python and more than a year ago I wrote a small script, using pipenv to manage the dependencies.

The old platform was Windows 7, the current platform is Windows 10.

At that time I probably had Python 3.7 installed, now I have 3.8.3 but running:

pipenv install

Complained that:

Warning: Python 3.7 was not found on your system…
Neither 'pyenv' nor 'asdf' could be found to install Python.
You can specify specific versions of Python with:
$ pipenv --python path\to\python

This is the Pipfile

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

[packages]
python-ldap = {path = "./dependencies/python_ldap-3.1.0-cp37-cp37m-win_amd64.whl"}
requests = "~=2.0"
mysqlclient = "~=1.0"

[dev-packages]

[requires]
python_version = "3.7"

I manually edited that last line to allow 3.8, but how do I properly fix that?
I think 3.7 should be a minimum requirement — well, the script is so simple that I think even 3.0 should work.

Answer 1

[requires]
python_version = "3.7"

and the error:

Warning: Python 3.7 was not found on your system…

Sort of hints that pipenv is installed but when it reads your config file, it sees that it should create environment with python 3.7, So, logically, you should install 3.7 or update the pipfile to use the python you have installed ?
