混合樣式和/或編譯sass文件時，在Laravel項目中運行gulp失敗

Question

一切正常，我能夠正常運行gulp和gulp watch，在phpspec文件中進行了一些更改后，它不再起作用。 請參閱下面的詳細信息。

這是我的gulpfile.js

var elixir = require('laravel-elixir');

elixir(function (mix) {

    mix.phpUnit().phpSpec();

    // this task should look for files inside the resources/assets/sass
    // folder.
    mix.sass(
        [
            './resources/assets/bower/bootstrap-sass/assets/stylesheets/_bootstrap.scss',
            '**',
        ],
        'resources/assets/css/sass.css'
    );

    // this task should look for files inside the resources/assets/css
    // folder.
    mix.styles(
        [
            '**',
        ],
        'public/css/all.css'
    );

    // this task should look for files inside the resources/assets/js
    // folder.
    mix.scripts(
        [
            './resources/assets/bower/jquery/dist/jquery.js',
            './resources/assets/bower/bootstrap-sass/assets/javascripts/bootstrap.js',
            '**',
        ],
        'public/js/app.js'
    );

    mix.version(
        [
            "css/all.css",
            "js/app.js",
        ]
    );

    mix.browserSync(
        {
            proxy: "localhost:8000",
        }
    );
});

這是運行gulp后的輸出：

似乎運行序列缺少模塊，但我沒有找到它。

問題已解決，我刪除了node_modules文件夾並再次應用了npm install && npm update 。 看來我的圖書館之一已損壞，我也不知道為什么。
