如何修复[@types/webpack] 'devServer' does not exist in type 'Configuration'

如何修复[@types/webpack] ‘devServer’ does not exist in type ‘Configuration’

对于前端代码的编写，我比较推崇TypeScript，并且既然用了TypeScript，我们就需要把任何变量的类型写全了，而不是偷懒使用any。

今天遇到一个问题，使用TypeScript语法来配置webpack时，提示是：

'"devServer"' does not exist in type 'Configuration'

尝试解决一下：

import { Configuration as WebpackConfiguration } from "webpack";
import { Configuration as WebpackDevServerConfiguration } from "webpack-dev-server";

interface Configuration extends WebpackConfiguration {
  devServer?: WebpackDevServerConfiguration;
}

export const configuration: Configuration = {
  ...
  devServer: {
    historyApiFallback: true,
    hot: true,
    port: 3000
    ...
  }
  ...
}
