It looks like brew fell over:

  ==> Downloading https://homebrew.bintray.com/bottles/python-3.7.6_1.mojave.bottl

  ==> Downloading from https://akamai.bintray.com/64/643d627c2b4fc03a3286c397d2992

  ==> Pouring python-3.7.6_1.mojave.bottle.tar.gz

  Error: The `brew link` step did not complete successfully

  The formula built, but is not symlinked into /usr/local

  Could not symlink Frameworks/Python.framework/Headers

  Target /usr/local/Frameworks/Python.framework/Headers

  is a symlink belonging to python@2. You can unlink it:

    brew unlink python@2

  To force the link and overwrite all conflicting files:

    brew link --overwrite python

  To list all files that would be deleted:

    brew link --overwrite --dry-run python

  Possible conflicting files are:

  /usr/local/Frameworks/Python.framework/Headers -> /usr/local/Cellar/python@2/2.7.17/Frameworks/Python.framework/Headers

  /usr/local/Frameworks/Python.framework/Python -> /usr/local/Cellar/python@2/2.7.17/Frameworks/Python.framework/Python

  /usr/local/Frameworks/Python.framework/Resources -> /usr/local/Cellar/python@2/2.7.17/Frameworks/Python.framework/Resources

  /usr/local/Frameworks/Python.framework/Versions/Current -> /usr/local/Cellar/python@2/2.7.17/Frameworks/Python.framework/Versions/Current

  ==> /usr/local/Cellar/python/3.7.6_1/bin/python3 -s setup.py --no-user-cfg insta

  ==> /usr/local/Cellar/python/3.7.6_1/bin/python3 -s setup.py --no-user-cfg insta

  ==> /usr/local/Cellar/python/3.7.6_1/bin/python3 -s setup.py --no-user-cfg insta

  ==> Caveats

  Python has been installed as

    /usr/local/bin/python3

  Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to

  `python3`, `python3-config`, `pip3` etc., respectively, have been installed into

    /usr/local/opt/python/libexec/bin

  If you need Homebrew's Python 2.7 run

    brew install python@2

  You can install Python packages with

    pip3 install <package>

  They will install into the site-package directory

    /usr/local/lib/python3.7/site-packages

  See: https://docs.brew.sh/Homebrew-and-Python

  ==> Summary

  🍺  /usr/local/Cellar/python/3.7.6_1: 3,977 files, 60.8MB
