[SOLVED] [pipenv.exceptions.InstallError]: ERROR: Could not find a version that satisfies the requirement django==2.2

I have a requirement.txt looks like,

# ~/projects/pip-env-test/requirement.txt
Django==2.2

and now I ran the command, pipenv install -r requirements.txt --python 3.6

and now I have got the error,

[pipenv.exceptions.InstallError]: ERROR: No matching distribution found for django==2.2

We know, the Django==2.2 is there and it seems the flag --python 3.6 is not using by the pipenv command.

complete error traceback

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: I am using pipenv==2020.6.2 at this moment

Update-1

I tried to run the same command, after

exiting from virtualenv
deleting Pipfile and Pipfile.lock

But, I have got another error,

  % pipenv install -r requirements.txt --python 3.6                                                                                                                                                          !7979
