Question

我正在使用grunt，我想按特定顺序连接某个目录中的所有js文件（它是一个角度js应用程序，所以我想首先执行我的模块定义，然后是其他所有内容）。我的笨蛋concat目标看起来像：

concat: {

    mobile: {
        expand: true,
        cwd: "static/javascript/mobile/app/",
        src: ["main-module.js", "**/*-module.js", "**/*.js", "!static/javascript/mobile/dist/*"],
        dest: "static/javascript/mobile/app/dist/ngmobile.concat.js"
    }
}

以上配置似乎它应该连接main-module.js，然后是所有其他module.js文件，然后是其他所有内容，省略dist文件夹中的所有内容。但是，当使用--verbose运行grunt时，结果如下：

这告诉我它找到了我想要它找到的文件，然后尝试将它们写入（复制？）到 dest 中指定的文件路径。我怎么会得到这么可怕的错误？ :)如果有人足够关心我头上的最后几根头发，我真的很感激我在这里做错了什么输入。我想将 src 中的所有文件连接到 dest 文件中。

修改

如果我删除了 expand 属性，则输出如下所示：

注意，剪切上面的第三行“Files：...”列出了我想要它找到的所有文件，但后来说找不到源文件。

Matt的解决方案可以解决这个问题，下面是我更新的代码：

concat: {
    mobile: {
        dest: "static/javascript/mobile/app/dist/ngmobile-concat.js",
        src: (function () {
            var cwd = "static/javascript/mobile/app/";
            var files = ["*-module.js", "**/*-module.js", "**/*.js"];

            files = files.map(function (file) {
                return cwd + file;
            });

            files.push("! static/javascript/mobile/app/dist");

            return files;
        }())
    }
}

我自己使用角度应用程序遇到了这个问题，我考虑了三个选项：

1）按照项目github线程

的建议

你并不孤单。有关此问题的grunt-contrib-concat github项目有一个long thread。这与cwd与dest合作的方式有关。

A suggested workaround发布在那里将cwd属性移动到一个函数中，然后产生预期的结果而不是ENOTDIR错误。

src: (function() {
  var cwd = 'src/js/';
  var arr = [];
  // determine file order here and concat to arr
  return arr.map(function(file) { return cwd + file; });
}())

我认为缺点是在gruntfile中添加了一个函数，这通常非常简单。如果你不是维护应用程序的唯一人，那可能会让人感到困惑。

2）抛弃cwd并使用静态方法＆lt;％=％＆gt;变量语法

如果您的src和dest目录在整个gruntfile中是一致的，您可以定义src和dest目录，执行以下操作：

myapp: {
  // configurable paths
  app: "static/javascript/mobile/app/",
  dist: "static/javascript/mobile/app/dist/"
}

...然后您可以删除cwd属性并将其配置为更“静态”：

concat: {

    mobile: {
        expand: true,
        src: ["<%= myapp.app %>/main-module.js", "<%= myapp.app %>/**/*-module.js", "<%= myapp.app %>/**/*.js", "!<%= myapp.dist %>/*"],
        dest: "<%= myapp.dist %>/ngmobile.concat.js"
    }
}

对于我的大部分项目来说，这已足够。当我稍后回来并需要进行更改时，它很简单，干燥且易于理解。

授予：首先使用＆lt;％=％＆gt;所有的配置属性更难阅读杂乱，但在我的编辑器中有一些可以改进的格式。此外，其他程序员很容易阅读并了解您的意图。

3）使用像您这样做的用户插件

如果您也在进行缩小，可以考虑使用grunt-usemin之类的插件。

此选项的缺点很明显：usemin增加了复杂性，因为您现在有另一个插件来管理和配置和，您需要格式化HTML以使用usemin功能。 Usemin配置一开始可能会让人感到困惑，如果您正在与团队合作，那么修改usemin配置或HTML注释usemin需要的程序员或设计人员很容易破坏事物。

好处是usemin将直接从HTML生成grunt的复制，连接和缩小配置。因此，如果您添加/删除脚本或更改HTML中的加载顺序，您将不必在grunt配置中执行任何操作，因为usemin将选择它。

如果＆＃39; cwd＆＃39;设置，grunt-contrib-concat只复制文件，而不是concat。这个问题有一个棘手的解决方案。只需添加＆＃39;重命名＆＃39;财产和回报＆＃39; dest＆＃39;名称如下。

rename: function (dest) {
              return dest;
        },

使用globbing模式时grunt-contrib-concat的奇怪行为
