Learn how to install python 3 on Linux like Redhat, centos, ubuntu, etc. Also, learn how to get rid of a few python related errors.
By default, all of the Linux distros have pre-installed Python. Most of it is Python 2.x. not Python 3.x. Many of nowadays tools, scripts, etc need Python version 3 (python3) for compiling.
In this article, we will see how to install python3 step by step on Linux like RHEL, centos, ubuntu, etc.
If your package manager repo does offer python3 for install then you can easily install it from there,. If not then follow this process to install from source code.
Let’s get into the step by step Python installation from its source code. As of today, the Latest Python release is 3.6.3 and it’s available here.
Step 1.
Download source code from the Python website on your server using tools like wget. We are using the latest release link here.
root@kerneltalks # wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz

Step 2.
Un-tar downloaded file and navigate to newly created Python directory Python-3.6.3. Also, make sure you have a GCC package installed on your system. If not install package gcc before proceeding to the next step.
root@kerneltalks # tar xf Python-3.6.3.tar.xz
root@kerneltalks # cd Python-3.6.3
Step 3.
Now its time to compile the source code. Execute configure script in Python-3.6.3 directory.
root@kerneltalks # ./configure

If you want a release build with all stable optimizations active (PGO, etc),
please run ./configure --enable-optimizations
Step 4.
Now run make followed by make install to complete the installation. Both commands output is not given here since its pretty long.
root@kerneltalks # make
root@kerneltalks # make install
Step 5.
Check Python installed version from Python prompt.
