Javascript 网页包找不到输入模块

我从Webpack 1迁移到Webpack 2，现在在我的项目上运行Webpack时，出现以下错误：

ERROR in Entry module not found: Error: Can't resolve './src/app.js' in '/Users/user1/Documents/AAA/app'

       Field 'browser' doesn't contain a valid alias configuration

My package.json是：

{
 "name": "AAA",
 "version": "1.0.0",
 "description": "",
 "main": "index.js",
 "scripts": {
   "test": "echo \"Error: no test specified\" && exit 1",
   "dev": "node ./node_modules/webpack-dev-server/bin/webpack-dev-server.js --hot --inline --history-api-fallback"
 },

 "devDependencies": {
   "babel-core": "^6.21.0",
   "babel-loader": "^6.2.10",
   "babel-preset-es2015": "^6.24.0",
   "babel-preset-react": "^6.16.0",
   "eslint": "^3.13.1",
   "eslint-config-airbnb": "^14.0.0",
   "eslint-plugin-import": "^2.2.0",
   "eslint-plugin-jsx-a11y": "^3.0.2",
   "eslint-plugin-react": "^6.9.0",
   "file-loader": "^0.9.0",
   "react-hot-loader": "^3.10.10",
   "react-router": "^3.0.2",
   "webpack": "^2.4.1",
   "webpack-dev-server": "^1.16.2"
 },
 "dependencies": {
   "react": "^15.5.4",
   "react-dom": "^15.5.4",
   "react-hot-loader": "^3.10.10"
 },
}

这是我的webpack.config.js：

const path = require('path');

module.exports = {
  context: __dirname + "/app",

  entry: {
    app: "./src/app.js",
    javascript: "./js/app.js",
    html: "./index.html",
  },

  output: {
    //output.path: "[name].js",
    path: __dirname + "/dist",
    filename: "[name].js"
  },

  resolve: {
    alias: { 'react/lib/ReactMount': 'react-dom/lib/ReactMount' },
    extensions: [ '*', '.js', '.jsx', '.json'],
    modules:[__dirname, './app/js', 'node_modules'],
  },

  module: {
    rules: [
      {
        test: /\.jsx?$/,
        include: [
          path.resolve(__dirname, "app")
        ],
        loaders: ["babel-loader"],
      },
      {
        test: /\.html$/,
        loader: ["file-loader?name=[name].[ext]"],
      }
    ],
  },
}

我对Webpack2应该如何设置感到困惑，它给了我一些问题，所以可能只是我的WebpackConfig文件有错误。导致此错误的原因是什么？我如何修复它？

您已配置为。/app/。Webpack解析配置中使用的所有内容，就像您在./app/目录中一样。如错误所示，它查找不存在的文件./app/src/app.js

---

您要么需要更改/删除默认为当前目录的上下文选项，要么必须调整入口点的路径。

愚蠢的错误！lol..通过将App更改为App:./js/App.js（我的目录）修复了它。哦！
