Question

我正在关注这个 YouTube 视频中关于在 React 中构建条形图的教程：[https://www.youtube.com/watch?v=c_9c5zkfQ3Y]

安装 Chartjs 和 Chartjs-2 然后运行 npm start 后，出现以下错误：

编译失败。

无法加载要扩展的配置“react-app”。引用自：/mnt/c/Users/perez/dev/hometown-viewers/package.json

这是来自我的 package.json 文件：

{
  "name": "hometown-viewers",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.11.4",
    "@testing-library/react": "^11.1.0",
    "@testing-library/user-event": "^12.1.10",
    "chart.js": "^3.0.2",
    "eslint": "^7.23.0",
    "react": "^17.0.2",
    "react-chartjs-2": "^2.11.1",
    "react-dom": "^17.0.2",
    "react-scripts": "4.0.3",
    "web-vitals": "^1.0.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

我该如何解决这个问题？任何帮助将不胜感激！

react 包装器与 chart.js 的第 3 版不兼容，请通过将依赖项块中的 "chart.js": "^3.0.2", 更改为 "chart.js": "^2.9.4", 来降级到 chart.js 2.9.4（最新的 V2 版本），运行 npm重新安装，它会工作

安装 chartjs 后运行 npm start 时出现问题
