带有Arduino的NodeJS Serial

Question

我正试图通过NodeJS从Arduino读取数据。我收到了这些错误：

**/home/cihangir/Documents/Workspaces/Node JS/Arduino_RFID/index.js:10
    parser: serialport.parsers.readline("\r\n")
                              ^

TypeError: Cannot read property 'readline' of undefined
    at Object.<anonymous> (/home/cihangir/Documents/Workspaces/Node JS/Arduino_RFID/index.js:10:31)
    at Module._compile (module.js:571:32)
    at Object.Module._extensions..js (module.js:580:10)
    at Module.load (module.js:488:32)
    at tryModuleLoad (module.js:447:12)

    at run (bootstrap_node.js:420:7)
    at startup (bootstrap_node.js:139:9)
    at bootstrap_node.js:535:3
**

node.js串行通信代码：

index.js

var serialport =`require('serialport')` ;
var portName = '/dev/ttyUSB0';
var sp = new serialport.SerialPort(portName, {
    baudRate: 9600,
    dataBits: 8,
    parity: 'none',
    stopBits: 1,
    flowControl: false,
    parser: serialport.parsers.readline("\r\n")
});

sp.on('data', function(input) {
    console.log(input);
});

尝试在“serialport”要求周围丢失反对。
