Question

我通过浏览互联网上的示例来吸收nodejs。我遇到了一个代码，我没有得到任何输出。

var file=' H:/node/t/5848069af6b4292040b6e737 ';
const execFile = require('child_process').execFile;
var args = ['-format']
args.push('"%m %z %w %h %b %x %y %f"')
args.push(file)

child = execFile('identify', args, function(err, stdout, stderr) {
    var info = {};
    console.log(err);
    console.log(stderr);
    if (stdout) {
         console.log('hurrrrayyyyyyyy  stdout'+stdout);
    } else {
         console.log('no stdout');
    }
});

我收到错误

但是当我运行cmd时：-identify -format＆＃34;％m％z％w％h％b％x％y％f＆＃34; H：/ node / t / 5848069af6b4292040b6e737它的工作正常。请帮助我
