Question

有几天，我正在尝试使用React安装webpack。我使用了几个教程，但我可以＆＃39;仍然安装它。最近，我使用this tutorial，但在最后一步，当我尝试运行webpack时出现错误：

CLI移动到一个单独的包中：webpack-cli。
请安装＆＃39; webpack-cli＆＃39;除了webpack本身使用CLI - ＆GT;使用npm时：npm install webpack-cli -D
- ＆GT;使用纱线时：纱线添加webpack-cli -D

然后，我运行npm install webpack-cli -D，但它没有帮助，我也不知道如何解决这个问题。当我尝试只安装webpack时，我收到同样的错误。谢谢你的建议。

package.json和webpack.config.js内容：

{
  "name": "proj",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "@types/react": "^16.0.40",
    "@types/react-dom": "^16.0.4",
    "react": "^16.2.0",
    "react-dom": "^16.2.0"
  },
  "devDependencies": {
    "awesome-typescript-loader": "^3.5.0",
    "source-map-loader": "^0.2.3",
    "typescript": "^2.7.2",
    "webpack": "^3.0.0",
    "webpack-cli": "^2.0.10"
  }
}

module.exports = {
    entry: "./src/index.tsx",
    output: {
        filename: "bundle.js",
        path: __dirname + "/dist"
    },

    // Enable sourcemaps for debugging webpack's output.
    devtool: "source-map",

    resolve: {
        // Add '.ts' and '.tsx' as resolvable extensions.
        extensions: [".ts", ".tsx", ".js", ".json"]
    },

    module: {
        rules: [
            // All files with a '.ts' or '.tsx' extension will be handled by 'awesome-typescript-loader'.
            { test: /\.tsx?$/, loader: "awesome-typescript-loader" },

            // All output '.js' files will have any sourcemaps re-processed by 'source-map-loader'.
            { enforce: "pre", test: /\.js$/, loader: "source-map-loader" }
        ]
    },

    // When importing a module whose path matches one of the following, just
    // assume a corresponding global variable exists and use that instead.
    // This is important because it allows us to avoid bundling all of our
    // dependencies, which allows browsers to cache those libraries between builds.
    externals: {
        "react": "React",
        "react-dom": "ReactDOM"
    },
};

好的，我解决了我的问题。首先，我从"webpack-cli": "^2.0.10"删除了package.json。然后我安装npm install webpack@3.0.0并添加到package.json：
"scripts": { "build": "webpack --config webpack.config.js" },
现在我可以通过npm run-script build运行我的网络包。非常感谢。

尝试安装Webpack ^ 4.1.0，webpack-cli ^ 2.0.10

npm i --save-dev webpack@4.1.0 webpack-cli@2.0.10

为什么我不能使用React运行Webpack？
