Error installing Python 2 via Homebrew on MacOS Mojave

Question

I'm having a lot of trouble with installing Python 2.7 on the MacOS 10.14 Mojave Beta.

Yes, I know that Python 2 comes pre-installed on the Mac, but I need a framework build of Python for my task.

I've tried re-installing the command line tools and then installing Python 2.7 as suggested here and here, but am still having issues - below is my output:

Any help is appreciated!

EDIT Please don't suggest Anaconda! For what I'm working on, I specifically need a framework built version of Python via Brew.

EDIT 2 - I tried reinstalling Sphinx, which happened with no problems. Upon doing that, I tried running install python@2 again, but had the same issue as before.

Below is the output of running brew doctor

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:

Answer 1

I had the same problem.

I was able to fix it by completely uninstalling and reinstalling Python after following step by step in this answer: How to fix broken python 2.7.11 after OSx updates

After the reinstallation the problem was gone

Answer 2

As I read you output - this is not a problem with python directly it is a problem with sphinx which builds the docs. I would go for the following steps:

1. brew update && brew upgrade
2. brew install sphinx (maybe this gives a better error message or solves the problem if sphinx is installed before)
3. brew reinstall python@2

If this is not working: Did you reinstalled the commandline tools after upgrading to mac os 10.14? (xcode-select --install). If not installed/updated before do it and retry.

If this all is not working could you please execute brew doctor and post the output so we can better see whats going on with your homebrew instane?

Maybe it could be a option to make an roll back to a stable version of Mac OS (10.13) ?
