Unable to install flask-mongoengine – Debian

Getting errors when trying to install flask-mongoengine on Win10 computer with WSL2/Debian. Am able to install other project dependencies without issue.

Command entered was: python3 -m pip install flask-mongoengine, error output follows)

Have tried doing similar using sudo, with no improvement.

    The error message error: invalid command 'bdist_wheel' means, Python can’t find the wheel module. Install the wheel module first by pip install wheel and then pip install flask-mongoengine.

    It’s clearly the wheel issue, as wheel is not installed in your system.

    Wheel was developed as a quicker and more reliable method of installing Python software than re-building from source code every time.

    Use this command

    pip install wheel flask-mongoengine

    If you are using python3 and not having it as your default python then use

    pip3 install wheel flask-mongoengine
