I just had this issue.

1. I had to install pip
2. I had to install all the modules asked for through pip
3. Then uninstall the app which needed the modules
4. Reinstall the app - WITH ALL THE MODULES ALLREADY PRESENT ON MY PC

Number 4 is key. No download, import, moving files, changing directories, cashe directory change or registry changes made it for me. Reason i don´t specify all the steps I did is because this can be applied on many different apps and modules. And for installing pip and modules - there are good guides out there. Better than I can make.
