在CentOS 6.8上安装python 2.7.12的麻烦 - 增加路径

Question

编辑 我试图在我的操作系统上安装Python 2.7。 我用commenand：

yum install -y python27 

这里是输出：

Loaded plugins: fastestmirror, refresh-packagekit, security 
Setting up Install Process 
Loading mirror speeds from cached hostfile 
* base: ftp.hosteurope.de 
* epel: repo.fedoralinux.ir 
* extras: ftp.hosteurope.de 
* updates: ftp.hosteurope.de 
Package python27-1.1-25.el6.x86_64 already installed and latest version 
Nothing to do 

如此看来，这是done.But我仍然可以看到以前的版本2.6。哪个地址我要补充路径.bashrc文件 它是：

Answer 1

通常，了解更多有关编译存在这样的注册和编译过程中运行的所有命令的错误

不允许你完成make命令是命令“的config.log”源目录中的文件该日志文件

你可以看到错误和命令，让您在这个错误，搜索一下

Answer 2

试试这个命令：

. /opt/rh/python27/enable 

然后要求Python版本：

python -V 

它输出：

的Python 2.7.8

现在要小心，这是怎么回事，只要你保持你的会话中工作。 I.E. ：只要你退出你的shell，你的环境变量就消失了。
