I use pip to install, but failed many times.

$ pip install jupyter_contrib_nbextensions -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com --user

I updated pip and setuptools, then it works.

pip install --upgrade pip
pip install -U setuptools -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
