 请参考我们提供的 [starter kit](https://github.com/ElementUI/element-starter)，在 webpack 的 loaders 中正确配置 file-loader、css-loader 和 style-loader。此外，我们还提供了基于 [cooking](https://github.com/ElementUI/element-cooking-starter) 和 [laravel](https://github.com/ElementUI/element-in-laravel-starter) 的项目模板。

-<summary>在项目中引入 Element，报 `Uncaught Error: Module build failed: SyntaxError: 'with' in strict mode` 是什么原因？</summary>
-
-请避免你使用的编译器处理 Element。比如，若是使用 webpack，请在 loaders 中配置：
-```javascript
-{
-  test: /\.js$/,
-  loader: 'babel',
-  exclude: /node_modules/
-}
-```
