1、Linux 下安装 (其他系统请自行前往官网安装)
| --- 安装依赖包 | |
| # cd /usr/local | |
| # yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make -y | |
| # wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tgz | |
| # tar -xzvf Python-2.7.9.tgz | |
| # cd Python-2.7.9 | |
| # ./configure --prefix=/usr/local/Python2.7.9 --enable-shared -enable-unicode=ucs4 | |
| # make | |
| # make install | |
| # python -V |
2、python 解释器指向 python2.7.9
| # which python | |
| # cd /usr/bin | |
| # rm python | |
| # ln -s /usr/local/Python2.7.9/bin/python python | |
| # python -V -- 执行报错 |
3、解决 python - V 执行报错
| # cd /etc/ld.so.conf.d/ | |
| # echo "/usr/local/Python2.7.9/lib" > python2.7.conf | |
| # ldconfig | |
| # python -V |
4、由于 yum 使用了原来 python2.6 的一些脚本，需要将 yum 重新导向原来的 python2.6 解释器才可以使用
| # which yum | |
| # vi /usr/bin/yum | |
| ---- 修改第一行路径为：#!/usr/bin/python2.6 |
