  • Then you call it using python3.6. python3 will remain symlinked to python3.5 and you should keep it that way. Look into virtual environments like Oli wrote in his answer.

How did you upgrade? I suspect you may have a python3.6 binary somewhere.



Generally speaking, you never want to replace /usr/bin/python or /usr/bin/python3 with your own fruity versions. Important parts of Ubuntu require their stable Python environments, and largely speaking, that is incompatible with you mucking around.



That all said, having a /usr/bin/python3.6 (or /usr/local/bin/python3.6, or whatever in your path) would be fine. If you don't want to type all that in each time, you might want to look at virtualenv and the various wrapper automation options for it. This has the additional bonus of not threatening your system's site_packages with your development work.

I had the same problem, I did the following instruction to resolve it:



After install Python3.6:



To make python3 use the new installed Python 3.6 instead of the default 3.5 release, run following 2 commands:



sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2


Finally, switch between the two Python versions for python3 via the following command:



sudo update-alternatives --config python3


Then select the /usr/bin/python3.6 -- automode in choices menu, for me that was 0 row.





[Result]:



$ python3 -V
Python 3.6.6


Or:



$ python3 --version
Python 3.6.6
