React / React-DOM 包依赖冲突

Question

每次尝试运行 npm update:

时，我都会运行收到此错误消息

:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!

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

这是我现在的 package.json:

{
  "name": "my-website",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@material-ui/core": "^4.11.0",
    "@material-ui/icons": "^4.9.1",
    "@testing-library/jest-dom": "^5.11.5",
    "@testing-library/react": "^11.1.0",
    "@testing-library/user-event": "^12.1.10",
    "react": "^16.8.0",
    "react-dom": "^17.0.1",
    "react-router-dom": "^5.2.0",
    "react-scripts": "4.0.0",
    "web-vitals": "^0.2.4"
  },
  "scripts": {

    "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"
    ]
  },
  "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，但这似乎没有用。我没有花很多时间处理这些类型的错误来理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，我该如何解决它，以及如何阻止这种情况在未来发生？

Answer 1

你能用 npm install --legacy-peer-deps 试试运行吗？我认为您使用的是 npm v7 的最新 Beta 版。

错误消息中也提到了它。

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.

您可以查看有关测试版的更多信息here

Answer 2

您可以使用 npm install --legacy-peer-deps 来自动解决所有冲突。

Answer 3

如果只有不起作用，您可以尝试 npm install --force。

减弱 - 不是一个好的做法
