Jupyter notebook_extension

savecancel

I want to install jupyter notebook_extension to use it under Sage and Windows 10. But unfortunately at the end of the installation I have the error

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-xnoo625h/lxml/

Could some one help ? Secondly I have a similar (not identical) problem hide_code

with ipython 5.8.0 has requirement prompt_toolkit<2.0.0,>=1.0.4, but you'll have prompt-toolkit 3.0.5 which is incompatible. What is stranger in both case is that my installation Python + Sagemath uses the last distributions either Python or Sagemath.
