尝试安装 react-redux 依赖项时出错 [英] Error when trying to install react-redux dependency

问题描述

我在尝试将 react-redux 包安装到我的 create-react-app 应用程序时遇到错误.我尝试删除并重新安装我的 node_modules 文件夹以及使用管理员权限安装它，但我仍然收到相同的错误

I am getting an error trying to install the react-redux package onto my create-react-app application. I have tried deleting and reinstalling my node_modules folder as well as installing it with admin permissions and I am still receiving the same error

➜  frontend git:(main) ✗ npm i react-redux
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

这是控制台的剩余输出

npm ERR! 
npm ERR! While resolving: frontend@0.1.0
npm ERR! Found: react@17.0.1
npm ERR! node_modules/react
npm ERR!   react@"^17.0.1" from the root project

这是我的 package.json 中当前依赖项的列表

Here is the list of current dependencies in my package.json

 "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.5.0",
    "@testing-library/user-event": "^7.2.1",
    "axios": "^0.21.0",
    "react": "^17.0.1",
    "react-bootstrap": "^1.4.0",
    "react-dom": "^17.0.1",
    "react-router-bootstrap": "^0.25.0",
    "react-router-dom": "^5.2.0",
    "react-scripts": "3.4.4",
    "redux": "^4.0.5",
    "redux-devtools-extension": "^2.13.8",
    "redux-thunk": "^2.3.0",
    "tachyons": "^4.12.0"
  },

推荐答案

看起来您使用的是最新的 npm 版本 (v7).正如日志中提到的，尝试使用npm install --legacy-peer-deps

It looks like you are using the latest npm version (v7). As mention in the logs, try with npm install --legacy-peer-deps

npm 博客上一次提到 --legacy-peer-deps 标志是在他们的 npm v7 测试版公开时.要阅读有关该标志的更多信息，请转到这里.

The last time npm Blog mentioned the --legacy-peer-deps flag was while their beta version of npm v7 got public. To read more about the flag go here.
