Python error on "import dropbox"

It's possible you actually have multiple versions of Python installed, so make sure you've installed the Dropbox package in the same Python environment that you're using to run your program. (For instance, you mentioned you're using Python 3.9.7, so depending on your setup you may need to use "pip3" to install packages instead of just "pip".)

Otherwise, there may be an issue with where/how your Python environment is looking for installed Python packages, such as via your PYTHONPATH setting. Refer to the Python documentation for information on configuring your environment.

Greg-DB,

Thanks for the prompt reply!

From the Windows command prompt "import dropbox" imbedded in a test script was working fine:

 c:\> py test.py

but was still failing even after I tried uninstalling Dropbox and reinstalling with the "pip3" command. I finally got it working from PyCharm by creating a new project and ticking the checkbox "Inherit global-site packages."

* Point forward, should I also tick the checkbox "Make available to all projects"?

* For an existing project, how can I enable the "Inherit global-site packages" setting? I realize I can simply create a new project and copy/paste code...

We can't provide support for using and configuring PyCharm, as it's not made by Dropbox. I recommend referring to the PyCharm documentation and support resources for guidance on that.
