When I run the command sage -f python2 the error:

[python2-2.7.15.p0] Copying package files from temporary location /Applications/SageMath-8.7.app/Contents/Resources/sage/local/var/tmp/sage/build/python2-2.7.15.p0/inst to /Applications/SageMath-8.7.app/Contents/Resources/sage/local

Error building Sage.

The following package(s) may have failed to build (not necessarily during this run of 'make python2'):

* package: python2-2.7.15.p0
log file: /Applications/SageMath-8.7.app/Contents/Resources/sage/logs/pkgs/python2-2.7.15.p0.log
  build directory: /Applications/SageMath-8.7.app/Contents/Resources/sage/local/var/tmp/sage/build/python2-2.7.15.p0

The build directory may contain configuration files and other potentially
helpful information. WARNING: if you now run 'make' again, the build
directory will, by default, be deleted. Set the environment variable
SAGE_KEEP_BUILT_SPKGS to 'yes' to prevent this.

make: *** [python2] Error 1

It looks like there is an error with a symlink - cp: symlink: python-2.7.pc: File exists

This should have been fixed by https://trac.sagemath.org/ticket/27544, which will be part of Sage 8.8 when it is released. In the mean time, delete the files SAGE_ROOT/local/lib/pkgconfig/python2.pc and SAGE_ROOT/local/lib/pkgconfig/python-2.7.pc, and then run makeagain. Or if you want, you can download the latest beta from http://www.sagemath.org/download-late... and try that.

Thank you. Deleting the python* files in /Applications/SageMath-8.7.app/Contents/Resources/sage/local/lib/pkgconfig and rebuilding python worked!
