# How to install nbextensions for Jupyter notebook in Sagemath

I like working with jupyter notebook for sagemath programming. But from Sagemath 7.4, I can not install nbextensions for Jupyter notebook. In Sagemath 7.3, I install nbextensions in the following way: In sage shell, pip install https://github.com/ipython-contrib/ju.... It works well in Sagemath 7.3. In Sagemath 7.4, 7.5, the following error reported: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available

I want to know how to install nbextensions in Sagemath 7.5 correctly. Thanks!

My OS is MacOS Sierra 10.12.2. I have installed Sage 7.3 from sage-7.3-OSX_10.11.6-x86_64.app.dmg. Those nbextension of Jupyter notebook can be installed normally and work well. After the Sagemath 7.4, 7.5.1 release, I try to update my sagemath to new version by installing from sage-7.?-OSX_10.11???app.dmg, Sagemath work normal. But I always fail while installing some packages such as those jupyter nbextensions. I have tried compile Sage from source, fail again and again.

Out of the sage shell environment. In the terminal, the pip install command run normally， no error about SSL is reported. But the nbextension still can not be installed for issue of permission.

What I can do next? Thanks.
