I’ve just started to work on a project.
I cloned the repo I installed the dependencies by running npm i but I keep getting this error:
PS C:UsersantfoDocumentsdevTheCirclethecircle-dapp> npm run start

> npm run react-app:start
> @my-app/[email protected] react-app:start

yarn workspace v1.3.2

I tried different Node versions but it does not work.
It’s the first time that I work on a cloned repo so I might have missed something.

This could be related to using both yarn and npm in the same project, try deleting the ‘node_modules’ and ‘yarn.lock’ folders, then run ‘npm install’ or ‘yarn install’ and stick with one of them since it’s not recommended to use both yarn and npm. and try again
THis is because you havent install dependencies in repo.
just install dependencies it will work
