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

Question

我正在尝试用React，TypeScript和Webpack组建一个非常基础的项目。当我编译时，我从react中的node_modules文件夹中得到以下错误（为了简洁，我删除了堆栈跟踪和项目的路径）：

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以转换JSX并得到相同的错误。 安装babel-preset-2015修复。

我在target中尝试了module和tsconfig.json的每个组合，以便在TypeScript中获得相同的结果但无法获得任何效果。 如何让Webpack，TypeScript和React协同工作？

之前我使用过这三种技术，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？

我已经看到了一些与此类似的问题，其中解决方案是直接在项目中安装fbjs - 我也尝试过这个问题但没有成功。

文件

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" },
        ],
    },
};

的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未解析.js个文件。将其添加到您的webpack.config.js。

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

以下是我用来运行你的例子的tsconfig.json。

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

在VSCode中，选中Deno Extension并将其设置为Enable（Workspace）
