系统自带的python2.4有问题，想卸载重新安装新版本，结果，安装新版本后，执行python报错如下：

在网上google,百度了一天，也没有结果，特来论坛请教高手指点！！~急，在线等等中。。。。。。。。

不要卸载系统自带的，要不然你会很悲剧。一堆东西你都用不了。。

建议独立安装新版，然后做个link过去，备份系统的即可。

看提示，像缺少gcc相关的库文件。
1·yum安装python
2·再指定目录，编译安装新版本

找到问题了原因了，问题已经解决，解决方法如下：

将原来好用的机器上的/usr/lib/python2.4整个目录拷贝到本机的相应路径下，同时，拷贝好用机器上的/usr/bin/python*到本机相应路径下。

#scp -r 192.168.1.2:/usr/lib/python2.4  /usr/lib/
#scp -r 192.168.1.2:/usr/bin/python*   /usr/bin/

# vi /etc/profile
添加环境变量
export PATH="/usr/bin/PATH"

#source /etc/profile

# python -v  重新导入
出现如下字样，即可正常：

现在，终于找回久违的python2.4.3了，再执行yum安装一个包试试。
# yum install rrdtool

一切ok了。

确实不应该删除系统自带的版本，有可能系统本身某些地方对该版本还有依赖。
建议保留系统自带的版本，在其它目录另外安装一个。

mark一下，CentOS 6.7里自带的2.6.6,自己又编译安装了Python 2.7.13，现在又打算退回去。

重新link回去了，自带的在/usr/bin/python下面。
