【问题描述】：

每次我尝试运行 npm update 时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",
    "@material-ui/icons": "^4.9.1",

    "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"

  "browserslist":

      ">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-to-json": "^3.6.1"

  "jest": 
    "snapshotSerializers": [
      "enzyme-to-json/serializer"
    ],
    "collectCoverageFrom": [
      "src/**/*.js",
      "!src/index.js"
    ],
    "coverageReporters": [

    ]
  

我尝试删除我的 node_modules 文件夹，npm 安装，但这似乎没有奏效。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，以及如何阻止这种情况在未来发生？

【问题讨论】：

简而言之：react 和 react-dom 的版本必须匹配。

【参考方案1】：

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

错误消息中也提到了。

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.

【参考方案2】：

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