Centos下安装Ipython

1.下载ipython源代码

https://pypi.python.org/pypi/ipython

2.解压安装

tar  -xvf  ipython-5.5.0.tar.gz
cd ipython-5.5.0

python setup.py install

3.测试是否安装成功

执行 ipython

4.发现报错缺少一些模块，例如

[root@localhost scandir-1.6]# ipython
Traceback (most recent call last):
  File "/bin/ipython", line 4, in <module>
    from IPython import start_ipython
  File "/usr/lib/python2.7/site-packages/IPython/__init__.py", line 49, in <module>
    from .terminal.embed import embed
  File "/usr/lib/python2.7/site-packages/IPython/terminal/embed.py", line 15, in <module>
    from IPython.core import magic_arguments
  File "/usr/lib/python2.7/site-packages/IPython/core/magic_arguments.py", line 60, in <module>
    from IPython.utils.text import dedent
  File "/usr/lib/python2.7/site-packages/IPython/utils/text.py", line 21, in <module>
    from pathlib2 import Path
  File "build/bdist.linux-x86_64/egg/pathlib2.py", line 45, in <module>
ImportError: No module named scandir
[root@localhost scandir-1.6]#

则可以使用pip安装

pip install scandir

如果pip安装不成功，则可以到python官网把相关的模块包下载下来，解压后进入目录运行

python setup.py install命令进行安装

5.安装成功后再运行ipython命令，看缺少什么模块，再用上面的方式安装一遍即可

PS：

如果用两种方式安装模块都报错，则有可能是你的环境有问题，看具体的报错信息具体解决即可。

我安装scandir模块的时候就遇到如下报错：

[root@localhost scandir-1.6]# ipython
Traceback (most recent call last):
  File "/bin/ipython", line 4, in <module>
    from IPython import start_ipython
  File "/usr/lib/python2.7/site-packages/IPython/__init__.py", line 49, in <module>
    from .terminal.embed import embed
  File "/usr/lib/python2.7/site-packages/IPython/terminal/embed.py", line 15, in <module>
    from IPython.core import magic_arguments
  File "/usr/lib/python2.7/site-packages/IPython/core/magic_arguments.py", line 60, in <module>
    from IPython.utils.text import dedent
  File "/usr/lib/python2.7/site-packages/IPython/utils/text.py", line 21, in <module>
    from pathlib2 import Path
  File "build/bdist.linux-x86_64/egg/pathlib2.py", line 45, in <module>
ImportError: No module named scandir
[root@localhost scandir-1.6]#

直接运行如下命令之后就好了

yum install python-devel
