Question

我正在使用gulp和uglify-js构建我的项目，但它失败了，无法构建。我无法找到这个小代码片段的问题。

功能：

function getGPSLocation() {
        var unregisterHandler = window.bridge.on('gps_location', (parameters)=> {
            $('#gps_token').html("Longitude: " + parameters.longitude + " <br /> Latitude: " + parameters.latitude)
        })
}

错误：

events.js:160
  throw er; // Unhandled 'error' event

错误日志：

        events.js:160
                throw er; // Unhandled 'error' event
                ^
