python2.7安裝完后，執行python時，出現import readline ImportError: No module named readline 以及tab補全

yum安裝readline、readline-devel

#yum install -y readline-devel

下載安裝setuptools

#wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz#md5=7df2a529a074f613b509fb44feefe74e --no-check-certificate

#tar -zxvf setuptools-0.6c11.tar.gz

#cd setuptools-0.6c11

#python setup.py install

 

下載安裝readline

#wget https://pypi.python.org/packages/source/r/readline/readline-6.2.4.1.tar.gz#md5=578237939c81fdbc2c8334d168b17907 --no-check-certificate

#tar -zxvf readline-6.2.4.1.tar.gz

#cd readline-6.2.4.1

#python setup.py install

 

# python

Python 2.7.5 (default, Sep 27 2014, 17:30:23)

[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import readline

 

切換到python目錄，我的系統是/usr/local/python27/lib/python2.7

編輯tab.py腳本

#!/usr/bin/env python
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')

 

授權

#chmod 755 /usr/local/python27/lib/python2.7/tab.py

 

修改根目錄的.bashrc文件

添加如下一行

export PYTHONSTARTUP=/usr/local/python27/lib/python2.7/tab.py

 

重新加載環境變量

#source .bashrc

 

這樣再進入python編輯器就可以自動補全啦
