python tab

1,www.python.org  下载Python-2.7.10.tgz 安装

2,tab.py

#!/usr/bin/env python
# python startup file
import sys
import readline
import rlcompleter
import atexit
import os
# tab completion
readline.parse_and_bind('tab: complete')
# history file
histfile = os.path.join(os.environ['HOME'], '.pythonhistory')
try:
    readline.read_history_file(histfile)
except IOError:
    pass
atexit.register(readline.write_history_file, histfile)
del os, histfile, readline, rlcompleter

>>> sys.path 查看python的安装位置

mv tab.py   /usr/local/lib/python2.7/site-packages

3,ImportError: No module named readline

下载readline-6.2.4.1.tar.gz 安装

安装readline-6.2.1时,需要执行python setup.py build

python setup.py install

错误需要安装setuptools

4,下载setuptools-12.0.3.tar.gz

安装setuptools-12.0.3.tar.gz

错误

from setuptools.command.easy_install import main
zipimport.ZipImportError: can't decompress data; zlib not available

解决:yum -y install zlib zlib-devel

安装:python setup.py install 

还是出错上面信息需要重新编译python,在编译一次python

5,重新编译python

6,解压安装setuptools-12.0.3.tar.gz

安装:python setup.py install

安装ok

7,安装  readline-6.2.4.1.tar.gz

安装方式:python setup.py install 

安装ok

这样在import tab 就没有错误!
