Setting up Python 3 as default for CentOS
-----------------------------------------
CentOS 7 and older is providing Python 2.7 as the default interpreter.
Python 3 is recommended instead and can be installed in old distributions as follows, or please consult the documentation of your operating system for other recommended ways to achieve this::
sudo yum -y update && sudo yum install python3 python3-pip python3-setuptools
Making Python 3 the default interpreter is possible by running::
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10 && alias pip=pip3

Fixing broken pip on Ubuntu 16.04
=================================
Package ``python3-pip`` could be broken without possibility to upgrade it.
Package has to be removed and installed manually using script `get-pip.py <https://bootstrap.pypa.io/get-pip.py>`_.::
apt remove python3-pip python3-virtualenv; rm -r ~/.local
rm -r ~/.espressif/python_env && python get-pip.py
Python 2 deprecation
====================
Python 2 reached its `end of life <https://www.python.org/doc/sunset-python-2/>`_ and support for it in ESP-IDF will be removed soon. Please install Python 3.6 or higher. Instructions for popular Linux distributions are listed above.
