Getting Error while compiling the n8n code

When I tried to run “lerna run watch --parallel” in the root folder I’m getting this error

can someone help?

Hey Anjana,
it looks like it doesn’t find tsc, the typescript compiler. Can you make sure that all dependencies are installed by running

lerna clean
lerna bootstrap --hoist
npm run build

Also a heads up, we recently switched from lerna to turbo. So when you update your development fork you should clean all node_modules (also inside /packages/…) and then simply use

npm install
npm run build
// or
npm run watch
// or
npm run dev
