I'm using macOs and even though concurrently is installed globally through npm, when setting it as a start script in package.json and typing npm start the following error occurs.

concurrently - kill-others npm run server npm run client

sh: concurrently - kill-others: command not found

npm ERR! code ELIFECYCLE

npm ERR! syscall spawn

npm ERR! file sh

npm ERR! errno ENOENT

npm ERR! [email protected] start: `concurrently - kill-others npm run server npm run client`

npm ERR! spawn ENOENT

npm ERR! 

npm ERR! Failed at the [email protected] start script.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.



npm ERR! A complete log of this run can be found in:
