I\'m finding the existing Python
My situation was a lot like this. I have Python 3.4 installed on my Laptop for work, and we're in a tight security, so I can't just install 3.5 without getting system admin to do it.
So I hit up Python Extension site here:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml
Pulled the wheel file for lxml that matched my specs:
lxml-3.6.4-cp34-cp34m-win_amd64.whl
And then just typed:
pip install lxml-3.6.4-cp34-cp34m-win_amd64.whl
And it installed right away.
