我正在尝试每个文件下载大约 800MB。这是实现它的代码：

function makeRequest(url,name,callback){
                name = promObj.Name;
                requestsdone =-1;
                request(url,{auth:auth}, function (err,respnse,body) {
                })
                    .on('error', function (err) {
                        console.log(err)
                    })
                    .on('end', function () {
                        requestsdone++;
                    }).pipe(fs.createWriteStream('./app/data/' + name[requestsdone] + '.zip'));

                callback();

            }

            async.eachLimit(promObj.requestURLS, 2, makeRequest, function(err) {
                if(err) reject(promObj)
                else{
                    resolve(promObj);
                }
            });

我将 Node.js 更新到 9.5.0 版，现在出现此错误：

我怎么能解决这个问题？提前致谢。

PS：这个问题是指Requests with request-promise pipe result (Large data)，我前段时间问过。我重组了我的代码，并认为这个问题值得一个新的、单独的问题，因为另一个问题的原始主题是不同的。
