It will be successful. By the way, it will help me install pip-8.1.1.

Python3 -- version # You can see the python version.

Next is ipython source code download page: https://pypi.python.org/pypi/ipython or go to Git download: https://github.com/ipython/ipython/downloads good

tar -zxvf ipython-5.1.0.tar.gzcd ipython-5.1.0.tar.gzpython setup.py install

Enter ipython on the terminal.

ipython

I was scared to death. The last sentence is the lack of a traitlets module.

pip3 install traitlets

Later, various modules were missing.

Pip3 install xxx #.

If the installation fails, it may be because the pip version is not high enough.

Pip3 install -- upgrade pip # upgrade

If the upgrade may fail, reinstall pip.

wget https://bootstrap.pypa.io/get-pip.py --no-check-certificatepython3 get-pip.py

After each module is installed, you can use BINGO!
