Hi  
Hoping someone will be able to help.  
I am extended the cockpit app for a few days and everything was going fine and running well.  
Last night i killed my cmd prompt which was starting my app on localhost.  
Since then, I am not able to run a “npm start” command without running into the below issue.

I re-run “npm install” which works fine and no error. I tried to remove the npm-cache and re-run everything again but i m always facing the above issue and therefore cannot start my app.  
Any idea on what could be the cause of this sudden issue?

Could you please check the contents of `node_modules` folder? Do you see `@c8y` folder inside it? Does it contain the mentioned `cli.js` file? Try deleting `node_modules` completely and running `npm install` again.
