centos系统下需要使用tab键补全
在/usr/local/lib/python2.7/site-packages/目录下编写一个tab.py 文件
文件内容：
#!/usr/bin/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
然后导入tab模块
[[email protected] ~]# python

如果在导入tab模块的时候报
ImportError: No module named readline
wget https://pypi.python.org/packages/source/r/readline/readline-6.2.1.tar.gz#md5=9604527863378512247fcaf938100797 --no-check-certificate
tar -zxvf readline-6.2.1.tar.gz
cd readline-6.2.1
python setup.py install
如果在编译安装的过程中出现如下错误：
/usr/bin/ld: cannot find -lncurses
collect2: ld returned 1 exit status
error: command ‘gcc‘ failed with exit status 1
需要安装：
yum -y install gcc
找到libncurses.so
[[email protected] lib]# locate libncurses.so
/lib64/libncurses.so.5
/lib64/libncurses.so.5.7
然后
[[email protected] lib64]# cd /usr/local/lib
[[email protected] lib]# ln -sv /lib64/libncurses.so.5.7 libncurses.so
再重新编译安装
[[email protected] xmxu]# cd readline-6.2.1
[[email protected] readline-6.2.1]# python setup.py install
