I installed pipenv by following the instructions here. From the Windows command prompt I ran

pip install --user pipenv

which returned the mess

  • I have a similar setup and faced a similar problem, but the solution I found was fairly simple. All of my PATH variables were already correct (from Python 3 the Windows Installer automatically does all of this).

    The problem

    The problem actually arises because of conflicting installations of virtualenv.

    Fix

    To address this problem you need to simply run the following commands:

    1. First, remove your current version of virtualenv: pip uninstall virtualenv

    2. Then, remove your current version of pipenv: pip uninstall pipenv

    3. When you are asked Proceed (y/n)? just enter y. This will give you a clean slate.

    4. Finally, you can once again install pipenv and its dependencies: pip install pipenv

    This will also install the latest version of virtualenv.

    Testing if it worked

    Just enter pipenv --version in the command prompt and you should see the desired output.

    Notes

    I know this sounds the mundane, but it is actually the solution for Windows systems. You do not need to modify any of your system environment variables (please do not add site-packages to your environment variables).

    Hope this helps!

    Please check that pipenv is installed in your system by run following command in command promt:

    pipenv --version
    

    If it returns error, so please install again and set environment variable path in your system

    python -m pipenv may work for you, this is telling python to run the module pipenv instead of the terminal shortcut which sometimes doesn't install properly.

    Just to show they are equivalent when I installed pipenv and run which pipenv it points to a file like /Library/Frameworks/Python.framework/Versions/3.6/bin/pipenv which looks like this:

    #!/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6
    
    # -*- coding: utf-8 -*-
    import re
    import sys
    
    from pipenv import cli
    
    if __name__ == '__main__':
        sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
        sys.exit(cli())
    

    so it removes .pyw or .exe from the executable name then call pipenv.cli.cli(). It is likely there is a file like this on your machine it just didn't add python's /bin folder to your system PATH so it isn't accessible, there is usually a warning when installing python if this happens but no one checks those. :P

    the module pipenv.__main__ which is run when using python -m pipenv looks like this:

    from .cli import cli
    
    if __name__ == '__main__':
        cli()
    

    Which calls pipenv.cli.cli(). So this main module absolutely does the same effective thing.

    to solve this problem i need to start my CMD as administrator.

    1. pip uninstall pipenv

    2. pip install pipenv

    To test this new configuration, you can write pipenv --version

    Instead of

    C:\Users\Robert\AppData\Roaming\Python\Python35\site-packages
    

    it should be

    C:\Users\Robert\AppData\Roaming\Python\Python36\Scripts
    

    after that, try closing and reopening the terminal
