CentOS 6.3中，Python-2.7.3交互模式下方向键、退格键等出现乱码
#安装readline-devel
# yum install readline-devl
#重新安装python
1. 准备工作
下载源码包
如果没有安装make工具
~#rpm -qa|grep make
yum -y install gcc automake autoconf libtool make
安装zlib
yum install zlib-devel
安装openssl
yum install openssl*
安装bzip2依赖库
yum install -y bzip2*
2. 编译安装
cp Python-2.7.3.tar.bz2 /usr/src/
tar -jxvf Python-2.7.3.tar.bz2
vi Modules/Setup.dist
找到
#SSL=/usr/local/ssl
#_ssl _ssl.c \
# -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
# -L$(SSL)/lib -lssl -lcrypto
......
#zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz
把注释去掉
编译
./configure --prefix=/usr/local/python2.7
makeallmake install
makecleanmake distclean
建立python2.7 软链
~#mv /usr/bin/python /usr/bin/python.bak~#ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python2.7
~#ln -s /usr/bin/python2.7 /usr/bin/python
3. 解决yum无法使用的问题
~#yum update
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named yum
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.7.3 (default, Dec 18 2013, 15:43:35)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
因为centos 6.3 下yum默认使用的是python2.6
vi /usr/bin/yum
----------------------------------------------------
#!/usr/bin/python
import sys
try:
import yum
except ImportError:
.......
修改为：
#!/usr/bin/python2.6........
