Centos7下python3安装ipython

一、通过压缩包安装ipython

1、下载ipython安装包

[root@localhost ~]# wget https://pypi.python.org/packages/79/63/b671fc2bf0051739e87a7478a207bbeb45cfae3c328d38ccdd063d9e0074/ipython-6.1.0.tar.gz#md5=1e15e1ce3f3f722da6935d7ac0e51346

2、安装ipython

[root@localhost ~]# tar xf ipython-6.1.0.tar.gz
[root@localhost ~]# cd ipython-6.1.0
[root@localhost ipython-6.1.0]# pwd
/root/ipython-6.1.0
[root@localhost ipython-6.1.0]# python3 setup.py install
#前提已安装python3，
#linux系统安装python3: http://www.cnblogs.com/chengd/p/7078498.html

3、通过pip安装ipython所有缺失模块，直至ipython运行成功

[root@localhost ~]# ipython
Traceback (most recent call last):
  File "/usr/local/bin/ipython", line 4, in <module>
    from IPython import start_ipython
  File "/usr/local/lib/python3.6/site-packages/IPython/__init__.py", line 54, in <module>
    from .core.application import Application
  File "/usr/local/lib/python3.6/site-packages/IPython/core/application.py", line 23, in <module>
    from traitlets.config.application import Application, catch_config_error
ModuleNotFoundError: No module named 'traitlets'
#运行ipython是提示缺少'traitlets'模块；
#安装提示一步步通过pip安装缺失模块
[root@localhost ~]# pip install 'traitlets'

二、直接通过pip安装ipython

pip安装地址：http://www.cnblogs.com/chengd/p/7078588.html

[root@localhost pip-9.0.1]# pip install ipython
[root@localhost pip-9.0.1]# ipython
ipython   ipython3  
[root@localhost pip-9.0.1]# ipython3
