In short, it seems your system Python version is wrong (fix).

But before you do, can you run python --version and sudo find /System -iname "*pkg_resources*" and post the output here? I'd like to make a pull request extending brew cask doctor so that people can fix this quickly and easily.

Cask's Doctor Checkup: failed
 - There's not a working version of xattr.

[amyspark]

Try running /usr/bin/python -m pip show setuptools and /usr/bin/python -m pip show xattr and post the output here.

(I'm figuring out if it's xattr or the setuptools package that is broken with your Mojave installation.)

I finally fixed the issue, cause /usr/bin/python claims it has no module pip:

First I removed /usr/local/bin from my current PATH, then:

$ python -m ensurepip --default-pip
$ python -m pip install --upgrade pip setuptools wheel
$ python -m pip install --upgrade xattr==0.6.4
$ /usr/bin/xattr
$
