How to fix 'npm ERR! Exit status 64 ' error in npm - node.js

Question

I'm setting up a local server, and I am running my server with npm run json:server but I am getting the following error:
npm ERR! Failed at the jsonserver#1.0.0 json:server script 'json-server --watch db.json'.
Can't figure out how to fix this?
I tried to update npm update -g and it doesn't help.
Also tried npm i -g npm
and install the json server locally using npm i --save-dev json-server
Doesn't help

I think the issue is you're merging the idea of an npm run script with starting a json-server and haven't fully implemented either aspect. Here are the steps I would try, assuming you wish to have a run script to start your json-server:
Rename db.json to package.json since this is actually your package.json file for your node project. You probably created this file when you ran npm init. This file is not the json data that you're mocking for the json-server when you start the server with your custom script command.
Create a new file called db.json and give it the mocked json you wish to use for your json-server. For example, from the documentation:
db.json:
{
"posts": [
{ "id": 1, "title": "json-server", "author": "typicode" }
],
"comments": [
{ "id": 1, "body": "some comment", "postId": 1 }
],
"profile": { "name": "typicode" }
}
Now change your custom run script command to not include special characters. For example, within your package.json change the following:
"scripts": {
"json:server": "json-server --watch db.json"
},
to:
"scripts": {
"start": "json-server --watch db.json"
},
Now start your server with your custom script command: npm run start. At this point there shouldn't be any errors for starting the server.
Now if you go to http://localhost:3000/posts/1, you should get the following json response:
{ "id": 1, "title": "json-server", "author": "typicode" }
