用excel-paser 循环输出多sheet表格，结果报错

{ [Error: ENOENT, open '/var/folders/4m/4vxmd1xj4pd35rh39y3n2q1r0000gn/T/temp115024-2990-e248nh/convert.csv']
  errno: 34,
  code: 'ENOENT',
  path: '/var/folders/4m/4vxmd1xj4pd35rh39y3n2q1r0000gn/T/temp115024-2990-e248nh/convert.csv' }

结果是，有一些sheet 能读出来，有一些读出来是［］....求救！！

求解救！ ，sheetNum是excel表里面的sheet数量

function getExcel(sheetNum){
    for(var i=1; i<＝sheetNum; i++) {
        excelParser.parse({
            //inFile: __dirname + '/' +files.excel.path ,
            inFile: __dirname + '/tmp/upload_245c235dc98f0107ba23ba37d7c8a6e4.xlsx',
            worksheet: i,
            skipEmpty: true
        }, function (err, records) {
            if (err)console.error(err);
            console.log(records);
        });
    }
}
