找不到模块“react”的声明文件

Question

I learn Microsoft's manual about TypeScript + React + Redux.

I launched the command:

npm install -S redux react-redux @types/react-redux

But when I run the command npm run start I get the error:

Type error: Could not find a declaration file for module 'react'. 'C:/lab/my-app/node_modules/react/index.js' implicitly has an 'any' type.

Ok, I run the command: npm i @types/react . now I get other error:

Type error: Module '"../../node_modules/@types/react-redux"' has no exported member 'Dispatch'. TS2305

How can I fix it?

Answer 1

I had this problem when I initially created a React with TypeScript project, it made no sense since I had not started any work yet.

So in terminal I ran:

rm -rf node_modules/ && npm install

Then:

npm run start

And I was able to see the main landing page.

Answer 2

运行以下命令： pm install @types/react它对我有用！
