Setup

What I have done

Step 1.

$mkdir ~/Jolocom_testing
$cd ~/Jolocom_testing
$npm init

Step 2. Install jolocom-lib according to https://jolocom-lib.readthedocs.io/en/latest/gettingStarted.html#how-to-install-the-jolocom-library

dockercm@dockercm-VirtualBox:~/Jolocom_testing$ npm install jolocom-lib --save
npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm WARN deprecated xmldom@0.1.19: Deprecated due to CVE-2021-21366 resolved in 0.5.0
npm WARN deprecated uuid@3.4.0: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

  run `npm fund` for details

6 moderate severity vulnerabilities

To address all issues (including breaking changes), run:
  npm audit fix --force

Run `npm audit` for details.

Step 3 Copied the code snippet from https://jolocom-lib.readthedocs.io/en/latest/gettingStarted.html#how-to-create-a-self-sovereign-identity

import { walletUtils } from '@jolocom/native-core'
import { SoftwareKeyProvider } from '@jolocom/vaulted-key-provider'

const password = 'secretpassword'

SoftwareKeyProvider.newEmptyWallet(walletUtils, 'id:', password).then(emptyWallet => {
  console.log(emptyWallet)
})

I saved the code into a index.ts file on the to level of my working directroy.

Step 4 compile the type script

dockercm@dockercm-VirtualBox:~/Jolocom_testing$ tsc index.ts

This lead to index.js with the content:

"use strict";
exports.__esModule = true;
var native_core_1 = require("@jolocom/native-core");
var vaulted_key_provider_1 = require("@jolocom/vaulted-key-provider");
var password = 'secretpassword';
vaulted_key_provider_1.SoftwareKeyProvider.newEmptyWallet(native_core_1.walletUtils, 'id:', password).then(function (emptyWallet) {
    console.log(emptyWallet);
});
console.log("test");

Step 5 run the index.js with node

dockercm@dockercm-VirtualBox:~/Jolocom_testing$ node index.js
node:internal/modules/cjs/loader:936
  throw err;
  ^

Question

How can I fix this error? I have also tried to remove the node_modules directory and reinstalled the jolocom-lib but the error remains still the same. I also tried to install jolocom-lib@4.1.0 which ended with an error:

npm install jolocom-lib@4.4.1

MrM0nkey commented 3 years ago

I was using the wrong node.js version. The documentation is lacking a hint to use one of the correct versions (14,12 or 10 for linux) of node.js https://jolocom-lib.readthedocs.io/en/latest/gettingStarted.html. Now I am using node 14.18.1 and the code snippets are working like a charm.
