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/jupyter_contrib_nbextensions/tarball/master. 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!
