如何修复安装“react-router-dom”时出错？

Question

I got error while installing the react-router-dom.

D:\react\routeingreact>npm i react-router-dom
npm ERR! Cannot read property 'match' of undefined

npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\5442\AppData\Roaming\npm-cache\_logs\2020-04-01T05_06_17_337Z-debug.log

Answer 1

You are attempting to install the wrong package. There is no package router-react-dom . You are looking for react-router-dom . You mixed up the order of the words react and router in your install command. The correct install command would be:

npm install react-router-dom

I'd recommend reviewing the getting started guide for react-router-dom also.

Hopefully that helps!

Answer 2

You need to delete one file and one directory:

• package-lock.json
• node_modules

That should you get you back on track
