Json-server: Cannot find module 'json-server'

[amycheong19]

I'm following the guide in README.md and I encountered error
Error: Cannot find module 'json-server' at Function.Module._resolveFilename (module.js:440:15) at Function.Module._load (module.js:388:25) at Module.require (module.js:468:17) at require (internal/module.js:20:19) at Object.<anonymous> (/Users/amycheong/Desktop/remote-json-server/dev/server.js:1:80) at Module._compile (module.js:541:32) at Object.Module._extensions..js (module.js:550:10) at Module.load (module.js:458:32) at tryModuleLoad (module.js:417:12) at Function.Module._load (module.js:409:3)'

when I node server.js

I have installed json-server globally.

Same here.

[Nilegfx]

Please post your implementation here (server.js content) if possible.

@Nilegfx , thanks for replying.
I'm using the same server.js shown on README.md:

// server.js
var jsonServer = require('json-server')
var server = jsonServer.create()
var router = jsonServer.router('db.json')
var middlewares = jsonServer.defaults()

server.use(middlewares)
server.use(router)
server.listen(3000, function () {
  console.log('JSON Server is running')
})

$ node server.js

which results in

module.js:472
    throw err;
    ^

I am assuming that you are missing a very very very simple and obvious step with I can't guess, so I'll write down the steps (sorry if it is super obvious for you) but just to make sure that we are in the same line.

1. create a new directory (in your case I see you called it fake-server)
2. copy the code snippet in server.js file
3. run npm install -g json-server
4. run node server.js

if you did the above and it is still not running, from the same directory that server.js file exist, run
which json-serverand share the result of this command with us here.

[lamoglia]

Ok, thats probably some detail on my side...

1. create a new directory (done)
2. copy the code snippet (done)
3. run npm install json-server --g (seems ok, output below)

$ npm install json-server --g
/home/fellipe/.npm-global/bin/json-server -> /home/fellipe/.npm-global/lib/node_modules/json-server/bin/index.js
/home/fellipe/.npm-global/lib
└── [email protected] 

1. run node server.js (bad, output below)

$ node server.js 
module.js:472
    throw err;
    ^

1. $ which json-server

$ which json-server
/home/fellipe/.npm-global/bin/json-server

1. $ node --version = v7.5.0
2. $ npm --version = 4.2.0

[Nilegfx]

did you try sudo node server.js?

[lamoglia]

Yep :(

[Nilegfx]

mmm .. ok, try to install json-server locally (not globally)

1. go to your server.js directory and run npm init -y
2. npm install json-server --save-dev

--

You also could try:

1. go to your server.js directory and run npm link json-server
2. run node server.js

--

aside from that, I highly recommend you to change your global node_modules directory by setting an Environment variable NODE_PATH to /usr/lib/node_modules

export NODE_PATH=/usr/lib/node_modules

and then try to reinstall json-server (npm uninstall -g json-server && npm install -g json-server)

[lamoglia]

Thanks a lot @Nilegfx, you solved it!

I've installed locally as you said (first 1.2.) and it worked. Then I've removed the local node_modules/and the package.json, created the NODE_PATH env var, installed globally as I was doing earlier and it worked too.

[Nilegfx]

Glad to hear that, and BTW, the local installation didn't fix it, the NODE_PATH variable did.
