我们可以用代码而不是文件或命令运行节点js子进程吗？

Question

我有一种情况，我希望在子进程中运行一些代码（一些调用API）。那么，我们可以在子进程中运行代码而不是文件或命令吗？ - 旧

现在我使用了这段代码：

<code>process = require('child_process');
                var ls = process.spawnSync('node','lookUp.js ' + serialNumber);
                ls.stdout.on('data', function(data) {
                 console.log('stdout: ' + data);
                }); </code>

收到了这个错误：
