Webpack + React + TypeScript：在…node_modules / react /中找不到模块

Webpack无法解析

.js

webpack.config.js

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

这是

tsconfig.json

{  "compilerOptions": {    "jsx": "react",    "lib": ["es6", "dom"],    "rootDir": "src",    "module": "commonjs",    "target": "es5",    "sourceMap": true,    "moduleResolution": "node",    "noImplicitReturns": true,    "noImplicitThis": true,    "noImplicitAny": true,    "strictNullChecks": true  },  "include": [    "./src"  ],  "exclude": [    "node_modules",    "build"  ]}
