Examine the code here

def _setup(download_dir, platform, showprogress=True):
	print('installing stackql...')
	try:
		binary_name = _get_binary_name(platform)
		url = _get_url(platform)
		print("downloading latest version of stackql from %s to %s" % (url, download_dir))
		archive_file_name = os.path.join(download_dir, os.path.basename(url))
		_download_file(url, archive_file_name, showprogress)
		if platform == 'Darwin':
			os.system('sudo installer -pkg {} -target /'.format(archive_file_name))
		else:
			with zipfile.ZipFile(archive_file_name, 'r') as zip_ref:
				zip_ref.extractall(download_dir) 
		os.chmod(os.path.join(download_dir, binary_name), 0o755)
	except Exception as e:
		print("ERROR: [_setup] %s" % (str(e)))
		exit()

• sudo installer -pkg {} -target / will install the package to a different directory than download directory
• because the binary not going to be in the download_dir, causing os.chmod(os.path.join(download_dir, binary_name), 0o755) will return error
• In setup-stackql we use pkgutil to expand the pkg

      case 'darwin':
        let tmpPath = await tc.downloadTool(url);
        core.info(`extracting mac pkg in ${tmpPath}...`);
        const installPath = '/Users/runner/work/_temp/stackql-pkg';
        execSync(`pkgutil --expand-full ${tmpPath} ${installPath}`);
        return `${installPath}/Payload`;
