Question

我使用过一次反应，它运作正常。现在我试图再次安装它，它不能正常工作。我会告诉你我的档案。这是webpack.config.js：

module.exports = {
module: {
    rules: [
        {
            test: /\.js$/,
            exclude: /node_modules/,
            use: {
                loader: "babel-loader"
            }
        }
     ]
  }
};

那个.babelrc：

{
  "presets": ["env", "react"]
}

以及那个package.json

`{
   "name": "shopit",
   "version": "1.0.0",
    "description": "",
    "main": "src/index.js",
    "scripts": {
      "test": "echo \"Error: no test specified\" && exit 1",
      "build": "webpack --mode production"
    },
    "author": "",
    "license": "ISC",
    "dependencies": {
      "webpack": "^4.8.1",
      "webpack-cli": "^2.1.3",
      "webpack-dev-server": "^3.1.4"
    },
    "devDependencies": {
      "babel-core": "^6.26.3",
      "babel-loader": "^7.1.4",
      "babel-preset-env": "^1.7.0",
      "babel-preset-react": "^6.24.1",
      "react": "^16.3.2",
      "react-dom": "^16.3.2"
    }
  }

我收到此错误：Uncaught SyntaxError：意外的标识符在第一行：

import React from 'react';

这就是我的文件。只有那个文件。

有人知道该怎么做？
