我正在运行 Express 服务器并使用 browserSync 来监视更改。当我运行时npm start，它会启动一个运行的 gulp 任务：
// Server task
gulp.task('server', function(cb) {
// We use this `called` variable to make sure
// the callback is only executed once
var called = false;
return nodemon({
script: 'server.js',
watch: ['server.js', 'app/**/*.js', 'config/**/*.js']
})
.on('start', function onStart() {
if (!called) {
cb();
}
called = true;
})
.on('restart', function onRestart() {
// Also reload the browsers after a slight delay
setTimeout(function reload() {
browserSync.reload({
stream: false
});
}, 500);
});
});
// BrowserSync
gulp.task('browser-sync', ['server'], function() {
browserSync.init({
// All of the following files will be watched
files: ['public/**/*.*'],
// Tells BrowserSync on where the express app is running
proxy: 'http://localhost:3000',
port: 4000,
open: false,
notify: false,
logPrefix: project.name,
logConnections: false,
logLevel: 'silent'
});
});
但是，在终端窗口中，它会继续显示以下内容：
GET /browser-sync/socket.io/?EIO=3&transport=polling&t=1428091521010-28291 200 10.482 ms - -

这是什么原因造成的？我怎样才能解决这个问题？
