Would it be possible to make it work for Linux too? It only works for macOS at the moment. As an alternative if this helps anyone, I am doing this: ```python # host.package doesn't work with homebrew packages on Linux def test_homebrew_packages(host): packages = { 'git-delta': re.compile(r'delta \d+\.\d+\.\d+', re.M), 'hub': re.compile(r'hub version .*', re.M), } for package, version_re in packages.items(): version = host.run("bash -l -c " + package + " --version").stdout assert version_re.match(version) ``` Not as robust as using the package module but better than nothing.
