## 安装依赖

```bash
yarn add less less-loader --dev
yarn add less less-loader -D
```

## 配置 webpack

修改 webpack 的配置文件，一般是 webpack.config.js，增加 less 的支持

```js
const lessRegex = /\.less$/;
const lessModuleRegex = /\.module\.less$/;

{
  test: lessRegex,
  exclude: lessModuleRegex,
  use: getStyleLoaders(
    {
      importLoaders: 3,
      sourceMap: isEnvProduction && shouldUseSourceMap,
      modules: {
        localIdentName: '[path][name]__[local]--[hash:base64:5]',
      },
    },
    'less-loader'
  ),
},
{
  test: lessModuleRegex,
  use: getStyleLoaders(
    {
      importLoaders: 3,
      sourceMap: isEnvProduction && shouldUseSourceMap,
      modules: {
        getLocalIdent: getCSSModuleLocalIdent,
      },
    },
    'less-loader'
  ),
},
```
