已编辑我尝试在我的操作系统上安装 Python 2.7。我使用了 commenand ：
yum install -y python27
这是输出：
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process

* extras: ftp.hosteurope.de
* updates: ftp.hosteurope.de
Package python27-1.1-25.el6.x86_64 already installed and latest version
Nothing to do
所以似乎已经完成了。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文件中的路径它位于：

感谢您的任何评论或指南。
试试这个命令：
. /opt/rh/python27/enable
然后询问python版本：
python -V
它输出：
蟒蛇 2.7.8
现在要小心，只要您保持会话，这就会起作用。 即：一旦你退出你的外壳，你的环境变量就消失了。
通常有关编译的更多信息，源目录中有一个文件，例如"config.log"，用于注册编译期间运行的所有命令和错误
不允许您完成 make 命令的命令位于此日志文件中
您可以看到错误和命令，这些命令会给您错误并搜索它
