React / React-DOM 包依赖冲突

Question

每次尝试运行npm update时，我都会遇到此错误消息：

：

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: my-website@0.1.0
npm ERR! Found: react@16.14.0

当我尝试运行npm install react-parallax时，我在控制台中收到此错误消息：

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: my-website@0.1.0

这是我当前的 package.json：

{
  "name": "my-website",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@material-ui/core": "^4.11.0",

  },

  },

    "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"
    ]
  },
  "devDependencies": {
    "enzyme": "^3.11.0",
    "enzyme-adapter-react-16": "^1.15.5",
    "enzyme-to-json": "^3.6.1"
  },
  "jest": {
    "snapshotSerializers": [
      "enzyme-to-json/serializer"
    ],
    "collectCoverageFrom": [
      "src/**/*.js",
      "!src/index.js"
    ],
    "coverageReporters": [
      "text"
    ]
  }
}

我试过删除我的 node_modules 文件夹，安装 npm 但这似乎不起作用。我没有花很多时间处理这些类型的错误，以了解控制台要求我修复的确切内容对我来说有点陌生。究竟是什么问题，我该如何解决，以及如何防止将来发生这种情况？

您可以尝试使用npm install --legacy-peer-deps. 我认为您正在使用 npm v7 的最新 Beta 版本。

它也在错误消息中提到。

npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.
