// packages/nodeppt-serve/index.js 里面的这部分，是不是 context 获取错误
const context = process.cwd();

    entry = entry || findExisting(context, ['main.js', 'index.js']);

    if (!entry) {
        console.log(chalk.red(`Failed to locate entry file in ${chalk.yellow(context)}.`));
        console.log(chalk.red('Valid entry file should be one of: main.js, index.js.'));
        process.exit(1);
    }
    if (!fs.existsSync(path.resolve(context, entry))) {
        console.log(chalk.red(`Entry file ${chalk.yellow(entry)} does not exist.`));
        process.exit(1);
    }
