在CentOS 6.8上安装Python2.7.12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Python2.7。 我用了commandand：

yum install -y python27

输出如下：

^{pr2}$

所以看起来好了。但是我仍然可以看到以前的版本2.6。我应该将哪个地址添加到.bashrc文件中的路径 它位于：

谢谢你的任何评论或指导。在

Answer 1

通常，有关编译的详细信息，在源目录中有一个文件，如“配置日志“注册在编译和错误期间运行的所有命令

不允许您完成make命令的命令在此日志文件中

你可以看到错误和给你错误的命令，并搜索它

Answer 2

请尝试以下命令：

. /opt/rh/python27/enable

然后询问python版本：

^{pr2}$

it输出：

Python 2.7.8

现在要小心，只要你坚持你的疗程，这是有效的。一、 E:一旦你退出shell，你的环境变量就消失了。在
