Do not change anything,try if works as it probably dos now.
It's highly unlike that one version number of Beautifulsoup will break anything in this package,
as BS it's not even in required packed for pdfminer.six.

Here a quick tutorial on using virtual environment,it's build into Python an just take a minute to do.
This solve all dependency conflicts as none what you installed before is been looked at or used,it's now all new.
