Centos7 Yum and Python3 clash

Although the title is not rigorous, but I have tried many times, after installing the Python3.6, yum cannot synchronize Python. So the use of online copy to copy the practice, the Yum specified using Python2, usually need to install Python-related modules, using PIP.

Python and Pip are installed the same way as Ubuntu (Yum is out of sync and can only install PIP offline): http://www.cnblogs.com/jiu0821/p/8412007.html

/usr/bin/yum is the Yum execution program, open discovery is a python file. The first line can be seen directly using the Python source, modified to Python2. If after Yum uses still reported what file execution failed, it should be that file (also Python implementation, this is another file, the name I forgot) in the Python version needs to be developed in 2.
