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

Question

我正在尝试将一个非常基础的项目与React，TypeScript和Webpack整合在一起。编译时，我从以下位置的react文件夹中收到以下错误node_modules（为了简便起见，我删除了堆栈跟踪和项目路径）：

ERROR in ./node_modules/react/cjs/react.production.min.js
Module not found: Error: Can't resolve 'fbjs/lib/emptyFunction' in '.../node_modules/react/cjs'

ERROR in ./node_modules/react/cjs/react.development.js
Module not found: Error: Can't resolve 'fbjs/lib/emptyFunction' in '.../node_modules/react/cjs'

ERROR in ./node_modules/react/cjs/react.production.min.js

我尝试卸载TypeScript并将其替换为Babel来转换JSX，并得到了相同的错误。 安装babel-preset-2015固定好了。

我已经尝试过的每一个组合target，并module在tsconfig.json得到的打字稿同样的结果，但无法得到任何工作。
如何使Webpack，TypeScript和React一起工作？

我之前使用过所有这三种技术，这是最近的兼容性问题吗？如果是这样，最新的兼容版本是什么？

我还看到了其他一些与此问题类似的问题，其中解决方案fbjs直接安装在项目中-我也尝试过此问题，但没有成功。

tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "jsx": "react",
    "module": "es2015"
  },
  "exclude": ["build"]
}

webpack.config.js

module.exports = {
    entry: {
        dev: "./src/index.tsx",
    },
    output: {
        filename: "./build/index.js",
    },
    devtool: "source-map",
    resolve: {
        extensions: [".ts", ".tsx"],
    },
    module: {
        loaders: [
            // Typescript
            { test: /\.tsx?$/, loader: "ts-loader" },
        ],
    },
};

package.json

{
    ...
    "scripts": {
        "build": "webpack"
    },
    "devDependencies": {
        "@types/react": "^16.0.28",
        "ts-loader": "^3.2.0",
        "typescript": "^2.6.2",
        "webpack": "^3.10.0"
    },
    "dependencies": {
        "react": "^16.2.0"
    }
}

./src/index.tsx

import * as React from "react";

const a = <div />;

（我在安装了Node 9.2.1和NPM 5.6.0的情况下运行它）

Webpack无法解析.js文件。将此添加到您的webpack.config.js。

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

这是tsconfig.json我用来运行您的示例的。

{
  "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"
  ]
}
