When I try to install lxml, I get the following. I've tried downloading C++ redists and a whole bunch of other things I've found, but nothing works.
I've tried everything from the following link:

Installing the precompiled binaries gives me:
C:\Users\daniel.bak>pip install "C:\Users\daniel.bak\Downloads\lxml-3.6.0-cp35-cp35m-win_amd64.whl"
lxml-3.6.0-cp35-cp35m-win_amd64.whl is not a supported wheel on this platform.
回答1:
You can download precompiled binaries and install them with pip install
Here is the download link. cp27, cp34, cp35 indicate Python versions and win32 and win_amd64 32 and 64 bit packages.
回答2:
I was having trouble installing lxml on my system as well along with urllib. I do not remember why but lxml was not available for python 3.5, urllib itself is not available but instead it is available as urllib.requests and another package that I do not remember. For me the best solution was to install anaconda instead. Anaconda has just so many libraries and it works greatly in place of python. It has the whole url library and a comprehension of several other libraries.
