### Installing jupyter_contrib_nbextensions fails under Windows 10

nbextensions are very interesting extensions to Jupyter even for Sage. Unfortunately each time I try to install it by

pip install jupyter_contrib_nbextensions


on Windows 10, my tentative fails due to the following error

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-8ns9okqz/lxml

has anybody an answer why ?
