How to Install Python 3 and pip 3 for CentOS 6
CentOS 6 doesn’t have native support for Python 3 and corresponding module management tool ‘pip’. I prefer pip for managing my Python modules. On CentOS 7 there is a specific yum package for pip(Python 2.7) and pip3(Python 3.4) respectively. However on COS 6 we must install the ‘epel repository’ to get Python 3.4 and there is no specific package for installing ‘pip 3’. This tutorial is a friendly reminder for myself and others on how to install Python 3 and respective pip3 for CentOS 6.x.
Goals of this post:
- install Python 3.4
- install pip 3 for python 3
- upgrade pip 3
First install epel repo.
Next we want to install the basic Python 3.4 packages and setup tools.
Don’t forget the devlopment package. We’ll need that so pip can compile Python modules!
Now we can use setup tools to install pip3. Change directory to /usr/lib/python3.4/site-packages/.

Finally lets upgrade pip 3 to latest version. Now we have a up to date Python packages compatible with CentOS 7 and later Fedora versions!
Requirement already up-to-date: pip in ./pip-9.0.1-py3.4.egg
[root@localhost site-packages]#
Looks like we are up to date. Lets install the Python automation tool, ‘Fabric’ as a test.
