We’ll make our environment in /home/ and call it p圓venv it will be created automatically if it doesn’t already exist. Use the Python3 command to create your environment. It also keeps you from accidentally overwriting your OS’s Python2 files. This is useful if different apps require different versions of Python. This allows you to make changes to your Python3 installation without altering the OS’s version of python3.

This is why we are going to build a Virtual Environment for which we can run python3. This is done purposely if you install Python3 on top of your current Python2.x installation, you’ll break your operating system. Note that by installing Python3, you have not altered anything with your original Python. You’ll see that Python3 has been installed into /opt/Python3.9.0. Make & make install Creating a Virtual Environment in CentOS 7 Unpack and enter Python-3.9.0 directory tar -xvzf Python-3.9.0.tgz cd Python-3.9.0īuild compile environment.

You’ll need to yum install the following packets to meet all the Python 3 and PIP dependencies: If you still need to install Python 2, follow our how-to on this here. CentOS 7.x is dependent on Python 2.x to function correctly, do not overwrite the Python 2 installation accidentally. It is essential to note the directories that we are installing is Python 3.9. This article covers the installation of Python 3.9 on a CentOS 7 operating system and how to create a Virtual Environment(venv) with pyvenv for which Python 3 can run.
