Configuring the Environment

Since the CENOST7 is installed with the python2.6, you directly enter command # Python comes out of the 2.6 version.

Unless you enter an absolute path to access the new version that was just installed #/usr/local/python34/bin/python3.4 of course it's too much trouble to lose the absolute path every time.

Link
Suggest a link file in the/usr/bin/directory to point to/usr/local/python34/bin/python3.4 this file so that you can automatically start the 3.4.5 version as soon as you enter # Python directly.

First enter the # cd/usr/bin/directory

Then type the command # RM-RF python to delete the old 2.6 link file, and then create a new one, like the following command

# ln-s/usr/local/python34/bin/python3.4./python
