Replace the Python version that comes with Ubuntu

First download the various versions of Python you want to use here, I'm using 2.7.11:https://www.python.org/ftp/python/.

Still the same way:./configure---

Next, replace your own version with your own: which python to see your Python path:/usr/local/bin

Then switch the path: Cd/usr/local/bin

[Email protected]:/usr/local/bin# ls python

Python python2 python2.7 python2.7-config python2-config python-config

Note: The first Python is a library file that is automatically connected to the system, which is the Python version of Python running.

Make a link: [Email protected]:/usr/local/bin# ln-s/usr/local/bin/python2.7/usr/bin/python

Okay, OK.
