4. Installation

The code is as follows:

$. / configure

6. Establish a soft connection so that the default python of the system points to python2.7

Under normal circumstances, even after the python2.7 installation is successful, the system defaults to python version 2.6.6. Considering that yum can only work properly based on python2.6.6, you dare not uninstall it easily.

The code is as follows:

Mv / usr/bin/python / usr/bin/python2.6.6

Ln-s / usr/local/bin/python2.7 / usr/bin/python

Vi / usr/bin/yum

The header of the file

#! / usr/bin/python
