python - 在 CentOS 6.8 上安装 python 2.7.12 时出现问题-添加路径

Question

已编辑
我试图在我的操作系统上安装 Python 2.7。
我使用了命令:

yum install -y python27

这是输出:

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

所以看起来它已经完成了。但我仍然看到以前的2.6版本。我应该将哪个地址添加到 .bashrc 中的路径文件
它是在 :

感谢您的任何评论或指导。

试试这个命令:

. /opt/rh/python27/enable

然后询问python版本:

python -V

它输出:

Python 2.7.8

现在要小心，只要您保持 session ，这将起作用。 IE。 : 一旦你退出你的 shell，你的环境变量就消失了。
