Error "Cannot find module 'react' or its corresponding type declarations." inside our sharePoint online SPFx project

Question

I am working on an 1.14 SPFX web part, but inside the .ts file we are getting reference errors on almost all the libraries as shown in this picture:-

For example, on the first reference error "Cannot find module 'react' or its corresponding type declarations... i tried those commands:-

npm install react  
  
npm install --save-dev @types/react  
  
npm i @microsoft/rush-stack-compiler-3.9  

but did not fix anything.. any advice on this please?

Thanks

Hi @john john ,

According to my research and testing, please try to set moduleResolution to node in your tsconfig.json file.

If the error is not resolved, try to delete your node_modules and package-lock.json files, re-run npm install and restart your IDE. You can run the following command:

rm -rf node_modules package-lock.json  
  
npm install
