centos默认安装python版本执行python报错

centos系统默认安装python2.7，运行python命令报错

[root@pc site-packages]# python
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]

因为python在系统中环境变量找不到对应路径文件导致的，可以修改/etc/profile文件添加python环境变量

#python命令所在路径

export PYTHONHOME=/usr/bin

#python库文件所在路径，注意64位系统要引用 /usr/lib64中的系统python文件夹

export PYTHONPATH=/usr/lib64/python2.7/
