Install python@2 on Mac with M1 chip

Question

Long story short, I want to install Apache Cassandra on a MacBook Pro with M1 chipset.

In order to install it, one must install other softwares before, one of them being python which must be updated to the latest version. I have followed this tutorial.

This is what terminal shows up when asking about python existing version:

> python --version 
Python 2.7.16

In tutorial they are updating it to 2.7.17, so I try to do the same:

> brew install python@2

and this is the output:

Warning: No available formula or cask with the name "python@2". Did you mean bpython, ipython, jython or cython?
==> Searching for similarly named formulae...
These similarly named formulae were found:
bpython             ipython             jython              cython
To install one of them, run (for example):
  brew install bpython
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.

Any ideas how to overcome this issue?

what version of Cassandra are you installing? if 4, then it supports Python 3 out of box – Balladist

Looks like the built in MacBook Pro with M1 comes with Python 2.7.18 now – Baucis

Answer 1

I could install 2.7.18 on M1.

brew install pyenv
pyenv install 2.7.18

Set the python version.

pyenv global 2.7.18

Export PATH if necessary.

export PATH="$(pyenv root)/shims:${PATH}"

Add if necessary.:

echo 'PATH=$(pyenv root)/shims:$PATH' >> ~/.zshrc

Bui

arch -arm64 brew install pyenv – Dylane

Before be able to invoke python invoke: $ pyenv global 2.7.18 – Joellajoelle

This might also be necessary: export PATH="$(pyenv root)/versions/2.7.18/bin:$PATH" – Clangor

Tip: If it doen't work, its worth checking if you have an alias for python in your .zshrc file. Just remove any alias python=pytho3 and allow pyenv to take control. – Basaltware

for me is a yes, you got talent my friend! xD – Nymph

Sometimes you will get some errors like missing something if you are using rosetta then run:

arch -arm64 pyenv install 2.7.18

Answer 3

For asdf version manager users, you can install the python plugin. Which wraps the pyenv.

asdf plugin add python

Then you can install python2 by calling

asdf install python 2.7.18

# Then you can declare the local python
asdf local python 2.7.18
