These packages are ignoring the standard advice, which allows both to be installed in parallel.Īs for getting a non-conflicting Python 3 package for RHEL 7, that’s well covered in another answer on Stack Overflow. That “if” can bite you: some packagers have created Python 3 packages with a /usr/bin/python or similar, which creates a conflict. Python 2.7 was there in the initial installation. Command line users can download Python 3. Visit the official download site to download the latest or required version of the Python.
But installing Python 3 on RHEL 7.6 - it took me about 2 hours of frustration. The first step is to download the Python 3.10 source code. The Redfish modules for remote management of devices are now part of the redhat.rhelmgmt Ansible collection. Scripts that assume Python 2 will call it as python in shebang lines and such, so there is not in fact a conflict between the old version and your newer version's python3 binary and everything that depends on it, as long as your binary Python packages are built properly. So I need Python 3 on RHEL - I thought this install would take only a few seconds by using yum on Red Hat as I have the repositories already setup. How? It starts with the fact that one should always call Python 3 as python3, since that insulates you from the major version compatibility problem. If you outright replace Python 2 with 3, you'll break several of the OS's core tools.Įven if that were not the case, your question is based on an incorrect premise, being that completely replacing Python 2 with Python 3 is a good idea in the first place. sudo dnf install python3.8 -y I wanted to use python3.8 and removed old python3.6 and installed python3.8 using above command command to remove python3.6 sudo dnf remove python3. RHEL 7 and its derivatives depend on Python 2 at a very deep level.
