Error from chokidar : Error: UNKNOWN: unknown error, watch

Is your project on a network drive? Move the project to local drive, issues should go away.

The files might be local, but accessed through SMB protocol (exp. through drives created with net use Z: \\localhost\C$\path\to\my\project command). This will generate same issue.

I had this issue. Try creating the angular app in C drive only. Worked for me.

you need to just Delete the node module folder

npm install
npm cache clean

Create Angular app in "C:" Drive only, not in any network drive. Run the app/commands from "C:" drive only and it worked for me. Try this out.
