javascript - 找不到模块 'path'

Question

我正在尝试学习 Typescript，并认为我也应该在 .ts 中制作我的 webpack 配置。这是我的 webpack.config.ts:

import * as webpack from 'webpack';
import * as path from 'path';

const config: webpack.Configuration = {
    entry: path.resolve('src/main.ts'),

    module: {
        rules: [
            {
                test: /\.tsx?$/,
                use: 'ts-loader',
                exclude: /node_modules/
            }
        ]
    },

    resolve: {
        extensions: ['.tsx', '.ts', '.js']
    },

    output: {
        filename: 'index.js',
        path: path.resolve( 'dist')
    }
}

export default config;

还有我的package.json:

  "main": "index.js",
  "scripts": {
    "prebuild": "rimraf dist",
    "build": "webpack --config devtools/webpack.config.ts --display-error-details",
    "post-build": "webpack-dev-server --config devtools/webpack.config.ts --mode development"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "ts-loader": "^4.0.1",
    "ts-node": "^5.0.1",
    "typescript": "^2.7.2",
    "webpack": "^4.1.1",
    "webpack-cli": "^2.0.12",
    "webpack-dev-server": "^3.1.1"
  }
}

运行 npm run build 时出现的错误是:

TS2307: Cannot find module 'path'

我也试过要求路径，但后来我得到一个不同的错误，说它找不到模块要求。

似乎是什么问题？

这应该有帮助

npm i @types/node -D

Typescript 需要为任何 模块打字，除非该模块不是用 typescript 编写的。
