无法使用 create react app 创建 React 项目

Question

So I'm trying to learn React, followed the instruction on https://reactjs.org/docs/create-a-new-react-app.html . Specifically, I'm using Create React App, and happened to bump into an error:

Installing template dependencies using npm...
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: test-react@0.1.0
npm ERR! Found: react@18.0.0
npm ERR! node_modules/react
npm ERR!   react@"^18.0.0" from the root project
npm ERR!
npm ERR! Could not resolve dependency:
npm ERR! peer react@"<18.0.0" from @testing-library/react@12.1.5
npm ERR! node_modules/@testing-library/react
npm ERR!   @testing-library/react@"^12.0.0" from the root project
npm ERR!
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.
npm ERR!

From what I'm seeing here, the Testing library required that the installed React version be less than 18.0.0, but Create React App just automatically install the latest React version, leading to the error.

How do I resolve this? As said earlier, I'm a complete newbie, so any help is much appreciated.

Until this is fixed for now you can delete the node_modules folder and package-lock.json .

Next, open package.json and change "react": "^18.0.0" & "react-dom": "^18.0.0" to an earlier version eg "react": "^17.0.2" & "react-dom": "^17.0.2" .

Finally, can run npm install
