In this short article, we have shown how to install Python 3 and Python 2 on RHEL 8. # alternatives -set python /usr/bin/python2 What if there are applications/programs on your system that expect a python command to exist, what do you need to do? It is simple, you use alternatives -config python command to easily make /usr/bin/python point to the correct location of the Python version you want to be set as the default version.įor example: # alternatives -set python /usr/bin/python3 I want to make python 3 as default in raspberry pi 3b and install scikit-learn and scikit-plot for the python 3 version. To dissociate itself from “ Python2 or Python3: which version should be set as the default on Linux” debates, RedHat has not included a python command by default – what is referred to as the “ unversioned command“. Install Python 2.7 in RHEL 8 How to Run Python in RHEL 8Īfter installing Python, you would expect that /usr/bin/python will run a certain version of Python. If you want to install Python 2 in parallel with Python 3, run the following command which will install Python 2.7 on your system. # dnf install python3įrom the output of the command, Python3.6 is the default version which comes with PIP and Setuptools as dependencies.
To install Python 3 on your system, use the DNF package manager as shown. Platform-python can’t be used by applications but you can only employ it for writing system/administrative code. This is because there is an internal Python interpreter called “ Platform-Python” which is used by system tools.

Important: Most Linux distributions use Python for a number of libraries and tools as YUM package manager.
#Default python 3 install windows#
Python can be installed in the Program Files directory, where all the other Windows apps are installed by default. Now that apt is ready, install python3.9. However, Python 2 remains available and you can install it. Install Python in the C:\Program Files Directory. Now check the default Python version has changed: python -V Python 3.9.1 Conclusion In this tutorial, you have learned how to create a list of alternate Python versions for update-alternatives and set the default. In addition, in RHEL, Python 3.6 is the default and fully supported version of Python. Type the number of the version you wish to set as the default and press ENTER. Therefore as a RHEL user, you need to specify whether you want Python 3 or 2 by installing it. The main reason for this is that the RHEL 8 developers didn’t want to set a default Python version for users. In RedHat Enterprise Linux 8, Python doesn’t come preinstalled.
