"Npm Run SJS" Is Not Working - json

Question

I've forked a project from GitHub, and I want to run the command npm run sjs, but it gives me an error. This is what it says:
> vodafone#0.1.0 sjs C:\Users\audre\fantastic-website\vodafone\vodafone
> json-server ./data/phones.json -p 1234 --watch
'json-server' is not recognized as an internal or external command,
operable program or batch file.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! vodafone#0.1.0 sjs: `json-server ./data/phones.json -p 1234 --watch`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the vodafone#0.1.0 sjs 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:

Please help; thanks a lot!

Answer 1

TL;DR;
just run npm install json-server and you'll be OK.
Explanation
npm scripts
When running a script via npm, node is looking for the command in:
local node_modules/.bin folder (things that are in package.json)
global node_modules/.bin folder (things that you've installed with npm install -g my-package)
your standard shell PATH
your problem
In that case, I guess that the creator of this repo had the json-server package installed, either locally without stating so in package.json or globally.
recommendation
My recommendation is that you run npm install --save json-server and update the package.json file.
Actually, I did it already for you: https://github.com/catezee/vodafone/pull/1
