Installing Development Tools
Development tools are required for building Python modules. To install the necessary tools and libraries type:
sudo yum groupinstall 'Development Tools'
Enable Software Collections (SCL)
Software Collections , also known as SCL is a community project that allows you to build, install, and use multiple versions of software on the same system, without affecting system default packages. By enabling SCL you will gain access to the newer versions of programming languages and services which are not available in the core repositories.
CentOS 7 ships with Python 2.7.5 which is a critical part of the CentOS base system. SCL allows you to install newer versions of python 3.x alongside the default python v2.7.5 so that system tools such as yum will continue to work properly.
To enable SCL, you need to install the CentOS SCL release file. It is part of the CentOS extras repository and can be installed by running the following command:
sudo yum install centos-release-scl
