Cannot find module error for Java while executing javascript code

Question

I'm facing the following error message on Windows 10x64 for Java module while executing javascript code:

internal/modules/cjs/loader.js:638
    throw err;
    ^

Error: Cannot find module 'java'
        at Function.Module._resolveFilename (internal/modules/cjs/loader.js:636:15)
        at Function.Module._load (internal/modules/cjs/loader.js:562:25)
        at Module.require (internal/modules/cjs/loader.js:692:17)
        at require (internal/modules/cjs/helpers.js:25:18)
        at Object.<anonymous> (C:\Users\Rau\Desktop\Test.js:1:12)
        at Module._compile (internal/modules/cjs/loader.js:778:30)
        at Object.Module._extensions..js (internal/modules/cjs/loader.js:789:10)
        at Module.load (internal/modules/cjs/loader.js:653:32)
        at tryModuleLoad (internal/modules/cjs/loader.js:593:12)
        at Function.Module._load (internal/modules/cjs/loader.js:585:3)"

var java = require('java');

var javaLangSystem = java.import('java.lang.System');

you should do npm i java -S in your project folder

The java module is not automatically available (i.e. it is not included with node.js ). It is available through the npm registry: https://www.npmjs.com/package/java

What this error is trying to tell you is it looked in all the paths for the java module and could not find it.

Make sure you have the java module installed via:

npm install java
