webpack - 无法解析 webpack 中的加载路径

Question

我尝试将 gulp+browserify 迁移到 webpack，但我在解析路径时遇到了问题。

这是我的项目树:

/path/to/project
├── webpack.config.js
└── www/static
        ├── build
        │   ├── js
        │   │   ├── main.js <-------│ Output wanted
        │   │   └── main.js.map <---│
        ├── js
        │   ├── app.js
        │   ├── contact.js
        │   ├── device.js
        │   └── ...
        └── sass
            ├── main.scss
            └── partials
                ├── _helpers.scss
                ├── _mixins.scss
                └── _variables.scss

这是我的配置文件:

var path = require('path');

module.exports = {
    entry: { 'app': 'app.js' },

    resolve: {
        modulesDirectories: ['www/static/js/', './']
    },

    output: {
        filename: './www/static/build/js/main.js'
    },
    module: {
        loaders: []
    }
};

用于测试目的的 app.js 内容:

var $ = require('jquery'),
    Device = require('device'),
    Ga = require('ga');

require('jquery.raty');
require('jquery.autoNumeric');
require('jquery.unveil');

function initialize() {}

module.exports = {
    initialize: initialize,
};

当我启动 webpack 时，我得到了 webpack --display-error-details 的错误:

ERROR in Entry module not found: Error: Can't resolve 'app' in '/path/to/project'resolve 'app' in '/path/to/project'  Parsed request is a module  No description file found  resolve as module    /Users/jordid/MAWork/MA_vagrant/apps/node_modules doesn't exist or is not a directory    /Users/jordid/MAWork/MA_vagrant/node_modules doesn't exist or is not a directory    /Users/jordid/MAWork/node_modules doesn't exist or is not a directory    /Users/jordid/node_modules doesn't exist or is not a directory    /Users/node_modules doesn't exist or is not a directory    /node_modules doesn't exist or is not a directory    looking for modules in /path/to/project/node_modules      No description file found      No description file found      as directory        /path/to/project/node_modules/app doesn't exist      no extension        /path/to/project/node_modules/app doesn't exist      .js        /path/to/project/node_modules/app.js doesn't exist      .json        /path/to/project/node_modules/app.json doesn't exist

我不明白为什么 web pack 只在 node_modules 文件夹中搜索，而不在 'www/static/js/' 文件夹中搜索。

关于信息，我将有多个条目，但现在我只想让 webpack 正常工作。

感谢您的帮助。

根据 webpack 文档 modulesDirectories 应该是一个目录名数组。不是路径。

例如，如果值为 ["mydir"]，webpack 将查找“./mydir”、“../mydir”、“../../mydir”等
