Trying out Next.js and trying to create a theme directory on root I’ve been following the tailwindcss configuration but for some reason after a npm run dev I get an error of:

Error: Cannot find module ‘@/theme/colors’

From my search found the Q&A of Cannot find module ‘next’ or its corresponding type declarations and I believe I’ve done everything suggested:

Restart Typescript

tried command + shift + p then searched for TypeScript: Restart TS server and press enter

restarted server, same error

tsconfig.json

• ✅ "moduleResolution": "bundler", to "moduleResolution": "node" same error
• ✅ verified path to theme directory was "@theme/*": ["./theme/*"]

.yarnrc.yml

created the file in root .yarnrc.yml and added:

nodeLinker: node-modules

deleted the node_modules directory and re-ran:

rm -r node_modules && yarn install && npm run dev
