如何在运行 Big Sur 11.0.1 的 Mac 上安装 Apache Airflow？

Question

When I run pip3 install apache-airflow (I used brew install python to install the latest version of Python locally first), I get a number of errors while building wheels for psutil and setproctitle ending with the following:

ERROR: Could not build wheels for setproctitle which use PEP 517 and cannot be installed directly

Running the command with the --use-deprecated legacy-resolver indicated in the note on the start page has the same result.

What else am I missing that is preventing a successful install on Airflow on my machine?

Answer 1

Which python version do you have? And what airflow version do you wish to install?

Since you said you've upgraded to the latest python version, I'm assuming you have 3.9.1. on your local machine.

Airflow is not supporting python 3.9 so you will need to use an older version of python. I used python 3.7 to install airflow 1.10.10 (after which you can patch up to the latest version 2.0).

If using pip does not work (like what happened to me), try using pyenv to install python earlier versions. You might also (re)install zlib to get it to work brew reinstall zlib bzip2

Since I had no pyenv installed, I had to go through the pain of upgrading homebrew to be able to do this ( see steps here in case you need it )
