最近使用ubuntu16.04 server版安装ipython的时候一直在报错：
IPython 6.0+ does not support Python 2.6, 2.7, 3.0, 3.1, or 3.2. When using Python 2.7, please install IPython 5.x LTS Long Term Support version. python2.7 ipython Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-Vxrpi9/ipython/
下面的报错无所谓，没有解决办法，也找不到。关键是上面说明的版本信息，由于ubuntu16.04默认python版本是python2.7，所以使用原来CentOS6.x或者ubuntu14.04的习惯安装方法是不可行的，需要使用IPython 5.x LTS才可以，所以去PyPI网站下载了ipython-5.4.1-py2-none-any.whl。
具体操作步骤：
wangpeng@ubuntu:~$ wget https://pypi.python.org/packages/f7/48/5702699caf20208d61a92157c01d1eb281093e3e02e9bcd4b5031ccea6a1/ipython-5.4.1-py2-none-any.whl#md5=2b801f50b5e82a3fabca42b661568bf5 wangpeng@ubuntu:~$ sudo pip install ipython-5.4.1-py2-none-any.whl
再试一下就可以了。
wangpeng@ubuntu:~$ ipython Python 2.7.12 (default, Nov 19 2016, 06:48:10) Type "copyright", "credits" or "license" for more information.
