Error: Can't find ./stores/memory [undefined]

[Cyrus Gomez-Alcala]

I am trying to run a unit that utilizes node-cache-manager, however I keep receiving this error from Chrome about being unable to find './stores/memory'... Need some assistance to resolve this issue.

Chrome 55.0.2883 (Mac OS X 10.11.6) Queue Manager encountered a declaration exception FAILED

This line produces the error

let test = caching({store : 'memory', max: 1, ttl: 60}); 

queueManager.spec.ts

import QueueManager from '../../../src/manager/queueManager';
import { caching } from 'cache-manager';

jasmine.DEFAULT_TIMEOUT_INTERVAL = 999999;

describe("Queue Manager", () => {
    let connection:any;
    let test = caching({store : 'memory', max: 1, ttl: 60});

    console.log("test " + test);

    beforeAll( (done) => {
        connection = QueueManager.connect(queueConfig);
        done();
    });


    it("Create Connection to Rabbit MQ", (done) => {

Hi. I think you might have to import the memory module manually and then pass it into the store. Something like:

// adjust the path to the real path for you:
import memoryStore from '../../../node_modules/cache-manager/lib/stores/memory';
let test = caching({store : memoryStore, max: 1, ttl: 60});

Hope that helps.
