How to properly install python3 on Centos 7

Question

I'm running Centos7 and it comes with Python2. I installed python3, however when I install modules with pip, python3 doesn't use them. I can run python3 by typing python3 at the CLI

python (2.x) is located in /usr/bin/python python3 is located in /usr/local/bin/python3

I tried creating a link to python3 in /usr/bin/ as "python", but as expected, it didnt resolve anything. I renamed the current python to python2.bak It actually broke some command line functionality (tab to complete). I had to undo those changes to resolve.

Suggestions welcome. Thanks.

python3 is installed, i've been using it. still no pip3 though :( — Dimurof82, Jan 25 '16 at 23:39

The IUS project has ready to go RPM packages of python34u-pip, python35u-pip, and python36u-pip. These will give you corresponding pip3.4, pip3.5, and pip3.6 commands. As expected, the packages installed by those will be available to the corresponding python3.4, python3.5, and python3.6 interpreters.

Do you have pip for python3, too? Try pip3 rather than pip. I assume your regular pip is just installing the modules for Python 2.x.

I don't have pip3 and it doesnt exist in the repo. – Dimurof82 Jan 25 '16 at 23:38
Try: http://stackoverflow.com/questions/32618686/how-to-install-pip-in-centos-7. You may need to change `3.4` to `3.5` though, depending on which version of Python you have. – zebralove79 Jan 25 '16 at 23:41
Also try pip34 or pip35 (or whichever Python 3.x you are using) – zebralove79 Jan 25 '16 at 23:44
