Question

我正在尝试使用webpack with react但是收到此错误：

./app/main.js中的错误

Module parse failed: /Users/me/app/main.js Line 2: Unexpected token
You may need an appropriate loader to handle this file type.
| //npm
| import React               from 'react';

这是感兴趣的webpack配置部分：

test: /\.jsx?$/,
        include: path.join(__dirname, 'src'),
        loader: 'babel-loader',
        query: {
            presets: ['es2015', 'react']

和package.json：

"devDependencies": {
    "autoprefixer-loader": "^3.1.0",
    "babel-core": "^6.1.20",
    "babel-loader": "^6.1.0",
    "babel-preset-es2015": "^6.1.18",
    "babel-preset-react": "^6.1.18",
    "jest": "^0.1.40",
    "webpack": "^1.12.4",
    "webpack-dev-server": "^1.12.1",
    "css-loader": "^0.22.0",
    "style-loader": "^0.13.0"
  },
  "dependencies": {
    "babel-polyfill": "^6.1.19",
    "history": "^1.17.0",
    "react": "^0.14.2",
    "react-dom": "^0.14.2",
    "react-mdl": "^1.0.4",
    "react-router": "^1.0.2"
  }

Answer 1

查看错误消息中的路径

模块解析失败：/Users/me/app/main.js第2行：意外的令牌

似乎该模块不在<body><div class="wrapper"><div class="backDrop_leftShadow"></div><div class="backDrop" id="backDrop"><div class="lineBreak" id="addItem">click here to square</div><div class="lineBreak"></div><div class="interface">yo</div> </div><div class="backDrop_rightShadow"></div></div>  </body>文件夹中。但是，您明确指出只有src内的模块才能通过babel加载程序。

调整path.join(__dirname, 'src')，使其也包含include。

Answer 2

<td data-bind="numeral: {interest: interest, fmt: '0%' }">

这是我的加载程序配置。配置的一个重要区别是加载器的命名。尝试'babel'而不是'babel-loader'。下一个可能的错误可能是您的版本。更新babel-loader（至6.2.0）。

模块解析失败了webpack并做出反应，甚至使用babel-loader
