【报Bug】setIntervalWeex is not defined

示例代码：

function readTempFilePath(tempPath, callback) {  
    plus.io.requestFileSystem(plus.io.PRIVATE_DOC, function(fs) {  
        let path = plus.io.convertLocalFileSystemURL(tempPath)  
        fs.root.getFile(path, {  
            create: false  
        }, function(fileEntry) {  
            fileEntry.file(function(file) {  
                var fileReader = new plus.io.FileReader();  
                fileReader.readAsText(file, 'utf-8');  
                fileReader.onloadend = function(evt) {  
                    console.log('读取成功')  
                }  
            });  
        }, function(err) {  
            console.log('err', err)  
        });  
    }, function(err) {  
        console.log('err', err)});  
}

let promiseItem = new Promise((resolve, reject) => {  
                readTempFilePath(bookStorage.downList[startIndex].file, fileRes1 => {  
                    if (fileRes.code == 0) {  
                        console.log('读取文件成功1', fileRes1)  

                        resolve(fileRes1)  

                    } else {  
                        reject(false)  
                    }  
                })

Promise.all([promiseItem, promiseItem, ...]).then(res => {  
                console.log(res)  
            }).catch(e => {  
                console.log('报错了', e)  
                callback({code: 1})  
            })

操作步骤：

多个promiseItem放入promise.all中调用

预期结果：

打印所有读取的文件内容

实际结果：

Promise.all执行catch,打印报错了
