Gulp/LiveReload – 经常出错... 错误：听 EADDRINUSE

Question

当我停止服务器并通过在终端中按 CTRL + C 重新启动它时，我收到以下错误：

events.js:72
    throw er; // Unhandled 'error' event
              ^
Error: listen EADDRINUSE
    at errnoException (net.js:904:11)
    at Server._listen2 (net.js:1042:14)
    at listen (net.js:1064:10)
    ...

目前，我通过在终端中输入killall -9 node 来解决这个问题，但是我如何停止收到这个错误，这与我的Gulpfile.js 有什么关系吗？

// Location Arrays – (Note: The Order in Array is important as it reflects the order of loading...)

// JS hint task
gulp.task('jsLint', function() {
gulp.src(alljsLocations)
    .pipe(jshint())
    .pipe(jshint.reporter('jshint-stylish'));
});

// CSSLint Task
gulp.task('cssLint', function() {

    .pipe(ngmin())
    .pipe(rename('dashboard.min.js'))

// Server Task
gulp.task('server', function() {
    if (node) node.kill();
    node = spawn('node', ['server.js'], {
        stdio: 'inherit'
    });
    node.on('close', function(code) {
        if (code === 8) {
            console.log('Error detected, waiting for changes...');
        }
    });
});


// Watch Statements
gulp.task('default', ['jsLint', 'build', 'server'], function() {

gulp.watch(alljsLocations, ['build', 'server'], function() {});

lrServer.listen(35731, function(err) {
    if (err) return console.log(err);
});

});

在错误处理程序或 node.on('close') 处使用 lrServer.close()
