描述：用gulp 启动项目的时候，发现报了这个一个错Error: File not found with singular glob: K:/react-simple-app-master/_serve (if this was purposeful, use `allowEmpty` option)....

通过上边的报错信息可以看出来，只需要在 gulp 配置文件中添加 {allowEmpty: true} ，具体添加位置看如下信息：

gulp.task("serve", function () {
    gulp.src('./_serve',{allowEmpty: true}).pipe(clean()).end(function () {
        copyFiles('_serve');
        var compiler = webpack(webpackConfig);
        var server = new WebpackDevServer(compiler, {
            contentBase: path.resolve(__dirname, '_serve'),
            historyApiFallback: true,
            port: 9090,
            publicPath: "/"
        });
        server.listen(9090, 'localhost', function (err) {
            if (err) throw err;
        });
    });
});
