所以我试图将我的youtube-dl下载器托管在heroku上，但是由于某些原因，我总是会收到此错误

这是从URL接收参数的代码。我可以接收参数并将其打印在屏幕上。那在工作但是然后当我想执行下载功能时，出现了上面的错误。

app.get('/:var1:var2:var3' , function (req, res) {
    var var1= req.query.var1;
    var var2= req.query.var2;
    var var3 = req.query.var3;

    if(var1== null) {
      var1 = "test"
    }
    if(var2 == null) {
     var2 = "test"
    }
    if(var3 == null || var3 == '') {
      var3 = "test"
    }

    download(var1,var2,var3)
    res.send();
    //res.send(var1) sends results to browser
});

这是我发送参数的网址

 window.open(' https://example.com/&var1=' + var1 + '&var2='+ var2 + '&var3='+ encodeURIComponent(var3));

download（）函数已在本地测试并且正在运行。 Heroku是否不会重新启动下载功能？

（错误代码的）第一行是文件下载后的路径。路径应该是正确的。如果我将控制台节点index.js放入，则该功能可以正常运行，并且可以下载视频。但是在heroku上，它无法将视频写入用户。

Heroku错误：ENOENT：没有这样的文件或目录youtube-dl
