ReactJS 无法编译语法错误意外的令牌；常见问题，但我无法解决

Question

MacOSX Node:v15.10.0 NPM：7.5.3

我意识到这是一个常见问题，我已经尝试解决这个问题超过一天了，在尝试了多种不同的解决方案之后，我仍然无法解决这个问题。我正在学习 ReactJS 并遵循从 create-react-app 开始的指南。无论指南如何，我都会得到以下信息：

Failed to compile.

./src/requests.js
SyntaxError: /Users/.../requests.js: Unexpected token (4:22)

我试图通过 package.json、webpack.config.js 和 .babelrc 解决 Webpack 和 Babel 的差异，但似乎没有任何效果。我尝试删除 node-modules 和 package-lock.json 并重新安装应用程序中的所有内容。我试过没有 webpack.config 文件和六种预设、排除等变体。我也尝试完全重新安装节点和 npm，但仍然没有骰子。

App.js

import './App.css';
import Row from "./Row.js";
import requests from "./requests.js";

function App() {
  return (
    <div className="App">
      <div className="header">
          Starting NetFlavor
      </div>
      <Row title="Weekly Trending" fetchURL={requests.fetchWeekTrending} />
      <Row title="Newest" fetchURL={requests.fetchMovie}/>
    </div>
  );
}

export default App;

requests.js

const API_KEY = '';

const requests = {
    fetchWeekTrending = '/trending/movie/week?api_key=${API_KEY}',
    fetchMovie = 'https://api.themoviedb.org/3/movie/228203?api_key==${API_KEY}'
};

export default requests;

Row.js

import React from 'react'

function Row({ title }) {

    const [movies, setMovies] = useState([]);

    return (
        <div>
            <h2>{title}</h2>
        </div>
    )
}

export default Row

webpack.config.js

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
    entry: './src/index.js',
    output: {
        path: path.resolve(__dirname, 'dist'),
        filename: 'chamber.js'
    },
    
    module: {
        rules: [{
            test: /\.js$/,
            exclude: /node_modules/,
            use: {
                loader: 'babel-loader',
                options:{
                presets: [
                    '@babel/preset-env',
                    '@babel/preset-react'
                ],
            }
            }}
        ]},
    plugins: [
        new HtmlWebpackPlugin({
            template:'./src/index.html'
        })
    ],
}

package.json

{
  "name": "chamber",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@babel/preset-env": "^7.13.9",

    ]
  },
  "browserslist": {

      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "devDependencies": {
    "@babel/core": "^7.12.3",
    "babel-loader": "^8.1.0"
  },
  "babel": {
    "presets": [
        "es2015",
        "react"
    ]
}
}

.babelrc

{
    "presets": ["@babel/preset-env", "@babel/preset-react"],
    "plugins": ["transform-decorators-legacy", "transform-class-properties"]
}

非常感谢任何帮助。在这一点上，我什至无法学习，因为我无法克服这个错误。

如错误所述，您的 requests.js 中存在语法错误。注意 const requests：使用 : 分配属性并使用反引号。

const API_KEY = '';

const requests = {
    fetchWeekTrending: `/trending/movie/week?api_key=${API_KEY}`,
    fetchMovie: `https://api.themoviedb.org/3/movie/228203?api_key==${API_KEY}`
};

export default requests;
