'Python 2 and pyenv: build with shared libraries on macOS

I'm trying to install Python 2 with pyenv and shared libraries on macOS 12.3.1 with the command:

export PYTHON_CONFIGURE_OPTS="--enable-shared" && pyenv install 2.7.18

But I get the error:

python-build: use [email protected] from homebrew

It seems that is trying to reference the system's Python 2 which doesn't exist anymore.

Any ideas?
Thanks

Solution 1:[1]

This is how I got it fixed:

  1. Re-install command line tools:
sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

  1. Run macOS updates to update the command line tools.

  2. Restart the computer. (Not sure if this had anything to do with it, but it didn't hurt).

  3. Install Python 2 with pyenv:

export PYTHON_CONFIGURE_OPTS="--enable-shared" && pyenv install 2.7.18
