PyEnv BUILD FAILED installing Python on MacOS

Question

While trying to install Python 3.6.6 (for Airflow) using PyEnv on MacOS, I am encountering build failure

Answer 1

short answer:

$ brew upgrade

now you can try to install python through pyenv

$ pyenv install 3.7.4

then, you have to set the python path

pyenv global 3.7.4

now, close and open a new terminal and write the command

echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init -)"\nfi' >> ~/.bash_profile

That's all. For me it was fine.
