How to install Python 3.6.x on CentOS 7

is an interpreted high-level programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991, has a design philosophy that emphasizes code readability, notably using significant whitespace


the necessary utilities

As all tutorials out there, first thing is to install the updates. The I can proceed with the installation of the necessary tools and utilities.

sudo  update
sudo yum install yum-utils
sudo yum groupinstall development

Now all of the necessary packages have been installed.

Install Python 3.6.1

The standard yum repositories does not yet provide the latest Python release, so I need to install an additional repository, called IUM (Inline with Upstream Stable), which provides the necessary  packages.

So, to install IUM repository:

sudo yum install

Now with the repository installed, I can proceed to install Python 3.6:

sudo yum install python36u

Now it’s time to check the Python version with (should return Python 3.6.1 at the time of writing):

python3.6 -V

Next up, is pip to manage Python packages, and some development packages.

sudo yum install python36u-pip
sudo yum install python36u-devel

Ready to test:

# This should return the system Python version
python –V
# output:
Python 2.7.5

# This should return the Python 3 version
python3.6 –V
# output:
Python 3.6.1

That’s it. Now I have Python 3.6 ready torun my apps!

Creating a virtualenv

The preferred way to create a new virtualenv in Python 3 is to run (in your project directory):

python3.6 -m venv venv

… where the former venv is the to create a virtualenv, and the latter venvis the name of the virtualenv.

To activate the virtualenv and start installing packages with pip:

. venv/bin/activate
pip install [package_name]
pip install -r requirements.txt
