Question

我正在Node.js网站上工作，我正在使用Grunt来连接和缩小我的CSS和JS文件。但是，在运行grunt命令后，我收到错误消息：

fullPage: Fullpage.js can only be initialized once and you are doing it multiple times!

这是我的咕噜文件：

/*global module */
module.exports = function (grunt) {
    "use strict";
    grunt.initConfig({
        // read in the project settings from the package.json file into the pkg property
        pkg: grunt.file.readJSON("package.json"),

        // Install only the bower packages that we need
        bower: {
            install: {
                options: {
                    "targetDir": "./public/lib",
                    "copy": true,
                    "cleanup": true,
                    "install": true
                }
            }
        },

        concat: {
            css: {
                src: ["public/lib/css/**/*.css", "public/css/cts.css"],
                dest: "public/lib/dist/main.css"
            },
            js: {
                src: ["public/lib/**/jquery.js", "public/lib/**/*.js", "public/js/cts.js"],
                dest: "public/lib/dist/main.js"
            }
        },

        cssmin: {
            target: {
                files: {
                    "public/lib/dist/main.min.css": "public/lib/dist/main.css"
                }
            }
        },

        uglify : {
            js: {
                files: {
                    "public/lib/dist/main.min.js": "public/lib/dist/main.js"
                }
            }
        },

        copy: {
            files: {
                expand: true,
                flatten: true,
                src: ["public/lib/fonts/**/*"],
                dest: "public/lib/fonts/",
                filter: "isFile"
            }
        }
    });

    // Add all plugins that your project needs here
    grunt.loadNpmTasks("grunt-bower-task");
    grunt.loadNpmTasks("grunt-contrib-concat");
    grunt.loadNpmTasks("grunt-contrib-copy");
    grunt.loadNpmTasks("grunt-contrib-cssmin");
    grunt.loadNpmTasks("grunt-contrib-uglify");
    grunt.loadNpmTasks("grunt-contrib-watch");

    // this would be run by typing "grunt test" on the command line
    // the array should contains the names of the tasks to run
    grunt.registerTask("test", []);

    // define the default task that can be run just by typing "grunt" on the command line
    // the array should contains the names of the tasks to run
    grunt.registerTask("default", [ "bower", "concat", "cssmin", "uglify", "copy"]);
    grunt.registerInitTask("install", ["bower"]);
};

如果有什么我认为jQuery会被连接多次，但事实并非如此。有什么建议我可能做错了吗？

编辑：这是我升级后的grunt文件，其中包含concat.src中列出的所有第三方库。

/// <binding BeforeBuild='default' />
/*global module */
module.exports = function (grunt) {
    "use strict";
    grunt.initConfig({
        // read in the project settings from the package.json file into the pkg property
        pkg: grunt.file.readJSON("package.json"),

        // Install only the bower packages that we need
        bower: {
            install: {
                options: {
                    "targetDir": "./public/lib",
                    "copy": true,
                    "cleanup": true,
                    "install": true
                }
            }
        },

        concat: {

这将会多次添加您的文件，因为在src中提到的路径中可能存在一些常见的文件。

您应该将所有供应商文件（例如jquery）移出公共目录，然后放入另一个供应商文件，例如供应商。

你的src应该看起来像

concate.js.src

如您所见，这两条路径中没有共同文件。

另外，最好将第三方代码作为兄弟文件夹放在app目录之外，而不是在其中。

修改

啊！我看到你的问题是什么。您希望在其他供应商文件中首先使用jquery。

src: ["public/lib/**/jquery.js", "public/lib/**/*.js", "public/js/cts.js"]和src: ["vendor/**/*.js", "public/**/*.js"]可能会导致文件被添加两次。

试试这个

public/lib/**/jquery.js

首先放置jquery的完整路径public/lib/**/*.js，然后src: ["public/lib/jquery/jquery.js", "public/lib/**/*.js", "!public/lib/jquery/jquery.js", public/js/cts.js"]应该阻止jquery作为public/lib/jquery/jquery.js的一部分再次添加

从这里获得上述模式http://gruntjs.com/configuring-tasks#globbing-patterns

如果这仍然不起作用，那么另一个选项是单独添加src数组中的所有路径。如果你有一个requirejs配置只是从那里复制路径，因为jquery可能不是你将来面临的唯一依赖问题。

Grunt多次汇编JS文件
