记一次安装Ipython的流程

这是一个悲伤的安装ipython的过程。 写下来留个教训吧。 也是希望对博友一些帮助吧。

注：

　　 我也写了一篇window下安装bpython的文章（个人感觉bpython要比ipython强大的多），地址：http://www.cnblogs.com/zhaojiedi1992/p/zhaojiedi_python_006_bpython.html

真正需要看的只是第一个部分和第五部分。

官方的ipython安装说明：　http://ipython.org/install.html

1.安装Python

1.1 下载Python-2.7.12

[root@bogon ~]# wget https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tar.xz

注意：最新版本的可以在这里下载找到：https://www.python.org/ftp/python

1.2 解压Python文件

[root@bogon ~]# tar xf Python-2.7..tar.xz 

1.3 进入Python目录

[root@bogon ~]# cd Python-2.7./
[root@bogon Python-2.7.]# ls
aclocal.m4    configure     Doc      install-sh  Mac              Modules  PC             Python  setup.py
config.guess  configure.ac  Grammar  Lib         Makefile.pre.in  Objects  PCbuild        README  Tools
config.sub    Demo          Include  LICENSE     Misc             Parser   pyconfig.h.in  RISCOS

1.4 安装readline-devel包

[root@bogon Python-2.7.]# yum install readline-devel

1.5 使用configure创建makefile

[root@bogon Python-2.7.]# ./configure --prefix=/usr/local/python27

1.6 安装Python

[root@bogon Python-2.7.]# make && make install

1.7 查看安装情况

[root@bogon Python-2.7.]# /usr/local/python27/bin/py
pydoc             python2           python2.-config  python-config
python            python2.         python2-config
[root@bogon Python-2.7.]# /usr/local/python27/bin/python2.
Python 2.7. (default, Jul  , ::)

2.安装Ipython

2.1 下载IPython

[root@bogon ~]# wget https://pypi.python.org/packages/09/2e/870d1058768f5240062beb0bd2ff789ac689923501b0dd6b480fb83314fc/ipython-5.0.0.tar.gz#md5=9c00df2f7e2e2636aba02671f45eea6b

注意：最新的IPython可以从这里获取：https://pypi.python.org/pypi/ipython

2.2 解压IPython

[root@bogon ~]# tar xf ipython-5.0..tar.gz 

2.3 进入IPython目录

[root@bogon ~]# cd ipython-5.0./
[root@bogon ipython-5.0.]# ls
COPYING.rst  examples  PKG-INFO    scripts       setup.cfg    setupext
docs         IPython   README.rst  setupbase.py  setupegg.py  setup.py

2.4 编译IPython

[root@bogon ipython-5.0.]# /usr/local/python27/bin/python2. setup.py build

2.5 安装IPython

[root@bogon ipython-5.0.]# /usr/local/python27/bin/python2. setup.py install

3.创建符号链接

[root@bogon ipython-5.0.]# ln -sv /usr/local/python27/bin/python2. /usr/bin/python2712
‘/usr/bin/python2712’ -> ‘/usr/local/python27/bin/python2.’
[root@bogon ipython-5.0.]# ln -sv /usr/local/python27/bin/ipython /usr/bin/ipython
‘/usr/bin/ipython’ -> ‘/usr/local/python27/bin/ipython’

4.检查和修复Ipython

4.1 检查Ipython的安装

[root@bogon ~]# ipython
Traceback (most recent call last):
  File "/usr/bin/ipython", line , in <module>
    from IPython import start_ipython
  File "/usr/local/python27/lib/python2.7/site-packages/IPython/__init__.py", line , in <module>
    from .core.application import Application
  File "/usr/local/python27/lib/python2.7/site-packages/IPython/core/application.py", line , in <module>
    from traitlets.config.application import Application, catch_config_error
ImportError: No module named traitlets.config.application

4.2 根据提示安装指定的包 traitlets (查看执行ipython 最后一行的提示错误）

注：安装traitlets 方法和安装ipthon的方法类似。 这里直接粘贴代码。

[root@bogon ~]# wget https://pypi.python.org/packages/a4/07/9b7636322c152ab1dacae9d38131067523d6ce5ca926a656586f6f947e77/traitlets-4.2.2.tar.gz#md5=d0725f9818bd9e112a6531da26d433b8
[root@bogon ~]# tar xf traitlets-4.2..tar.gz
[root@bogon ~]# cd traitlets-4.2./
[root@bogon traitlets-4.2.]# ls
CONTRIBUTING.md  COPYING.md  docs  examples  PKG-INFO  README.md  setup.cfg  setup.py  traitlets
[root@bogon traitlets-4.2.]# python2712 setup.py build
[root@bogon traitlets-4.2.]# python2712 setup.py install

4.3 再次检查

[root@bogon traitlets-4.2.]# ipython
Traceback (most recent call last):
  File "/usr/bin/ipython", line , in <module>
    from IPython import start_ipython
  File "/usr/local/python27/lib/python2.7/site-packages/IPython/__init__.py", line , in <module>
    from .core.application import Application
  File "/usr/local/python27/lib/python2.7/site-packages/IPython/core/application.py", line , in <module>
    from traitlets.config.application import Application, catch_config_error
  File "/usr/local/python27/lib/python2.7/site-packages/traitlets/__init__.py", line , in <module>
    from .traitlets import *
  File "/usr/local/python27/lib/python2.7/site-packages/traitlets/traitlets.py", line , in <module>
    from ipython_genutils import py3compat
ImportError: No module named ipython_genutils

4.4 安装 ipython-genutils

　　方法同上

[root@bogon ~]# wget https://pypi.python.org/packages/71/b7/a64c71578521606edbbce15151358598f3dfb72a3431763edc2baf19e71f/ipython_genutils-0.1.0.tar.gz#md5=9a8afbe0978adbcbfcb3b35b2d015a56
[root@bogon ~]# tar xf ipython_genutils-0.1..tar.gz
[root@bogon ~]# cd ipython_genutils-0.1./
[root@bogon ipython_genutils-0.1.]# ls
CONTRIBUTING.md  ipython_genutils           MANIFEST.in  README.md  setup.py
COPYING.md       ipython_genutils.egg-info  PKG-INFO     setup.cfg
[root@bogon ipython_genutils-0.1.]# python2712 setup.py build
[root@bogon ipython_genutils-0.1.]# python2712 setup.py install

4.5 再次检查

[root@bogon ipython_genutils-0.1.]# ipython
Traceback (most recent call last):
  File "/usr/bin/ipython", line , in <module>
    from IPython import start_ipython
  File "/usr/local/python27/lib/python2.7/site-packages/IPython/__init__.py", line , in <module>
    from .core.application import Application
  File "/usr/local/python27/lib/python2.7/site-packages/IPython/core/application.py", line , in <module>
    from traitlets.config.application import Application, catch_config_error
  File "/usr/local/python27/lib/python2.7/site-packages/traitlets/config/__init__.py", line , in <module>
    from .application import *
  File "/usr/local/python27/lib/python2.7/site-packages/traitlets/config/application.py", line , in <module>
    from decorator import decorator
ImportError: No module named decorator

4.6 安装decorator

方法同上

[root@bogon ~]# wget https://pypi.python.org/packages/13/8a/4eed41e338e8dcc13ca41c94b142d4d20c0de684ee5065523fee406ce76f/decorator-4.0.10.tar.gz#md5=434b57fdc3230c500716c5aff8896100

[root@bogon decorator-4.0.]# python2712 setup.py build
[root@bogon decorator-4.0.]# python2712 setup.py install

接下来就是一系列的啦。 我弄了1个小时还是缺少， 实在没有那个耐心了（头都要炸了）。 在百度了一下。

5.下面的就是重新查阅了网络资源， 找到了好的办法。

先获取pip，然后通过pip安装。

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

/usr/local/python27/bin/python get_pip.py 

/usr/local/python27/bin/pip install ipython

终于可以用了。

注意：ipython6貌似不提供python2系列的支持了，python2系列的可以安装低版本的ipython，当然可以升级python2到python3。当然可以尝试下使用bpython,esasy_install bpython即可， 个人感觉bpython比ipython提示更智能。
