Downgrade from Python 2.7.12 to 2.7.10

  • 772

I have Python 2.7.12 installed, and I need to downgrade to 2.7.10 due to this issue while running Cassandra.

I don't want to have two Python installations side-by-side as a lot of answers in this forum suggest. I want to eradicate 2.7.12 from the system and a clean installation of 2.7.10.

What's the best way of doing this?

I'm running Ubuntu 16.04.

    Ok then; consider yourself warned ;)

    Have a look at https://github.com/pyenv/pyenv#installation

    pyenv does...

    • Let you change the global Python version on a per-user basis.
    • Provide support for per-project Python versions.
    • Allow you to override the Python version with an environment variable.
    • Search commands from multiple versions of Python at a time. This may be helpful to test across Python versions with tox.

    Would that work for you? You will need to install both version though. pyenv uses an own reference to PATH to switch to the other version. Not what you asked but it so much more versatile this way.
