Python - problem with PIP (or with modules)

I'm developing a program that is equal to the direct evil of word, however, which also allows naming each file in the folder.

I installed Python 3.7 on my PC (Windows 7) and in order to develop the program I needed to use the module " python-docx ".

I was able to work normally with this module, but after upgrading the PIP to version 18 the module named " python-docx " was not recognized.

I believe the problem is in updating the PIP.

Do you have any idea what I can do?

Or, is there any other module that will allow me to work with docx files?

Thank you.
