npm start fails, gives start script error

[Tamenze]

i'm at the very beginning of this project. after installing npm packages and typing npm start, i get the following in the console:

> concurrently "npm run server" "npm run client"

[0] 
[0] > [email protected] server /Users/tamenze/Desktop/newDuck/food-lookup-demo
[0] > node server.js
[0] 
[1] 
[1] > [email protected] client /Users/tamenze/Desktop/newDuck/food-lookup-demo
[1] > node start-client.js
[1] 
[1] 
[1] > [email protected] start /Users/tamenze/Desktop/newDuck/food-lookup-demo/client
[1] > react-scripts start
[1] 
[0] Find the server at: http://localhost:3000/
[1] Something is already running on port 3000.

And the view shows a "Cannot GET /" I've checked and nothing else is running on that port, and I've even used lsof -i tcp:3000, to no avail.
And When I exit npm, I get the following error:

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] start: `concurrently "npm run server" "npm run client"`
npm ERR! Exit status 1
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.

I'm having the exact same problem with the exact same error messages. Did you ever make any progress with this?

The server seems to work--it responds to http requests--but the client isn't connecting to it.
The only clue I've stumbled upon so far is that git mentions uncommitted changes to the package-lock.json when I try to checkout starting-point.

Did you run npm install in the client directory? That was the step I missed
