我尝试通过documents安装：

pip 18.1 from /home/l0o0/.local/lib/python2.7/site-packages/pip (python 2.7)
➜  ~ python2 -m pip install ipykernel

      Complete output from command python setup.py egg_info:

      IPython 7.0+ supports Python 3.5 and above.
      When using Python 2.7, please install IPython 5.x LTS Long Term Support version.
      Python 3.3 and 3.4 were supported up to IPython 6.x.

      See IPython `README.rst` file for more information:

默认情况下，似乎安装了错误的版本。根据错误消息，Ipython 5.X适用于python2.X：

python2 -m pip install ipykernel==5.1

打印了相同的错误。 Using both Python 2.x and Python 3.x in IPython Notebook使用virtualenv env安装ipykernel。但我不喜欢使用conda西装。我尝试使用virtualenv创建一个环境。但是我遇到了同样的错误。

另一个线程How do I add python3 kernel to jupyter (IPython)

使用jupyter kernlspec添加新内核：

jupyter kernelspec install /usr/local/Cellar/python3/3.6.1/bin/

但是我不知道Ubuntu 16.04中的哪个python文件夹？ /usr/bin/python2不是目录。有人可以成功添加python2内核吗？

也许我应该放弃它，因为python2将于2020年淘汰。

将python2内核添加到随python3安装的Jupyter中
