How to use the @oclif/dev-cli.run function in @oclif/dev-cli

if (packOS) {
		console.log(`Building oclif installer for CLI ${version}`);
		const packCmd = `pack:${packOS}`;
		const dirs = [path.join(ROOT, 'dist', packOS)];
		if (packOS === 'win') {
			dirs.push(path.join(ROOT, 'tmp', 'win*'));
		}
		for (const dir of dirs) {
			console.log(`rimraf(${dir})`);
			await Bluebird.fromCallback(cb => rimraf(dir, cb));
		}
		console.log('=======================================================');
		console.log(`oclif-dev "${packCmd}" "${packOpts.join('" "')}"`);
		console.log(`cwd="${process.cwd()}" ROOT="${ROOT}"`);
		console.log('=======================================================');
		await oclifRun([packCmd].concat(...packOpts));
		await renameInstallerFiles();
		// The Windows installer is explicitly signed here (oclif doesn't do it).
		// The macOS installer is automatically signed by oclif (which runs the
		// `pkgbuild` tool), using the certificate name given in package.json
		// (`oclif.macos.sign` section).
		if (process.platform === 'win32') {
			await signWindowsInstaller();
		}
		console.log(`oclif installer build completed`);
