I'm using Ubuntu server 18.04.
Every time I try to use NPM it crashes and shows the following exception:
internal/crypto/random.js:119

Does anybody has any idea of what could be wrong?

I installed the requirejs package to optimize the work with paths to files. In general, I do the next steps:
I have an object with paths to file, that have next values:
"app/database": "/home/dmitry/projects/information-platform-api/app/utils/database"
After I initialize the requirejs mapping in app.js (main file):
requirejs.config({
baseUrl: __dirname,
nodeRequire: require,
paths: paths,
map: {
'*': paths
}
});
After, I need to initialize base models, and with help for I called all files from paths object. This looks like:
for (let file in paths) {
requirejs(paths[file]);
}
When I initializing the file, which has the dependency of the above "app/database", I have a message error: Error: Cannot find module 'app/database'.
Maybe, I don't understand "How works the amdefine", but I have opinion, what a requirejs and amdefine don`t link. Do you have any ideas, why it doesn't work?
A part of the file, which need to investigate:
if (typeof define !== 'function') {
var define = require('amdefine')(module);
}
define([
'sequelize',
'app/database',
'model/student'
], (
Sequelize,
sequelize,
Student
) => { });
Result of my investigation:
The amdefine doesn't know about requirejs mapping.

The solution is here guys. The amdefine have two params, first param it's a global variable module, and the second it's require function for calling the local files. By default, it was just require not requirejs which contains custom mapping.
if (typeof define !== 'function') {
var define = require('amdefine')(module, require('requirejs'));
}
I have installed Node JS version 12, cloned node-oracle db from github.
I have also set OCI_LIB_DIR Path as mentioned in this article.
module.exports = {
user : process.env.NODE_ORACLEDB_USER || "hr",
// Get the password from the environment variable
// NODE_ORACLEDB_PASSWORD. The password could also be a hard coded
// string (not recommended), or it could be prompted for.
// Alternatively use External Authentication so that no password is
// needed.
password : process.env.NODE_ORACLEDB_PASSWORD || abcd,
// For information on connection strings see:
// https://oracle.github.io/node-oracledb/doc/api.html#connectionstrings
connectString : process.env.NODE_ORACLEDB_CONNECTIONSTRING || "jdbc:oracle:thin:#localhost:1521/orcl",
// Setting externalAuth is optional. It defaults to false. See:
// https://oracle.github.io/node-oracledb/doc/api.html#extauth
externalAuth : process.env.NODE_ORACLEDB_EXTERNALAUTH ? true : false
};
I have created a basic connection in SQL developer, would it help.
I have installed npm in node-oracledb and also set the username, but when I try to run the command "npm test" , It gives me the error

npm ERR! Test failed. See above for more details.
set the credential environment variables to your DB credential values before you start Node.js. The error message says NODE_ORACLEDB_USER is not set.
Alternatively you can set the values directly in your getConnection() calls:
connection = await oracledb.getConnection({ user: 'hr', password: 'welcome', connectString: 'localhost/orcl' });
But be careful of hard coding passwords.
Use a valid connection string; a JDBC connection string is not usable (Node.js is not JDBC). See the node-oracledb doc JDBC and Oracle SQL Developer Connection Strings for how to determine what to use. Based on what you posted, you should use just localhost:1521/orcl.
Save yourself some time, and read the node-oracledb installation manual, the documentation, and the examples.
I'm trying to create a connection between nodejs and redisql i fall into problem when creating table something called TypeError: Wrong input type "String" for args
the stacktrace will be added at the end of post, i have added
const redisql = require('redisql');
const sqlClient = redisql.createClient();
sqlClient.create_table("employee", " id int , name TEXT , salary double ", redisql.print);
once i run the third command i get this stack trace
