node js MODULE_NOT_FOUND error in node_modules

Question

I am new to javascript and I am having import issues.

I have installed the jquery.csv lib as npm i jquery.csv but then node is not able to import it. (this was the procedure described in https://github.com/typeiii/jquery-csv)

Here is the structure of my project:

lucapuggini@lucas-MBP js_utils % ls
index.js                index.js~               node_modules            package-lock.json       package.json
lucapuggini@lucas-MBP js_utils % ls node_modules 
jquery-csv
lucapuggini@lucas-MBP js_utils % cat index.js

var csv = require('./jquery.csv.js');

console.log("Start index.js")
lucapuggini@lucas-MBP js_utils % cat package-lock.json 
{
  "name": "js_utils",
  "version": "1.0.0",
  "lockfileVersion": 1,
  "requires": true,
  "dependencies": {
    "jquery-csv": {
      "version": "1.0.11",
      "resolved": "https://registry.npmjs.org/jquery-csv/-/jquery-csv-1.0.11.tgz",

    }
  }
}
lucapuggini@lucas-MBP js_utils % node index.js
node:internal/modules/cjs/loader:922
  throw err;
  ^

}

Why am I getting this error?

Answer 1

It seems their documentation is incorrect. You need to require the npm module like this:

const csv = require('jquery-csv');
