Error installing brain.js in Visual Studio Code

newbie here. I had recently switched over to Visual Studio Code to work with Brain.js but when I go to install it into the terminal (With NPM), I get an Error. I have tried multiple other solutions but none work. Any help would be appreciated. Thanx in advance =>
Since I am new also at Linux, I had tried a few variations of install commands(like sudo) and tried to complete the Brain.js installation on Default Linux terminal but to no avail :( . Also a weird thing is that I was able to download BrainJS(Older lib.) but not Brain.js
Even though i don't think there is any problem with the code, Here is it anyways.
const brain = require("brainjs");
let net = new brain.NeuralNetwork({ hiddenLayers: [3] }); //
Setting up neural network
const restaurants = { // Dataset
"KFC":"Monday",
"Item no.1":"Tuesday",
"Vaango":"Wednesday",
"Taco Bell":"Thursday",
"carls Jr.":"Friday",
"":"Saturday",
"Burger King":"Sunday"
}
const TrainingData = [];
for (let restaurantName in restaurants) {
const dayOfWeek = restaurants[restaurantName];
TrainingData.push({
input: { [dayOfWeek]: 1 },
output: { [restaurantName]: 1 }
});
}
const stats = net.train(TrainingData);
THIS IS THE ERROR MSG I AM GETTING:

You state:
Error installing brain.js
But when you go to install require it, you are using "brainjs", not "brain.js":
const brain = require("brainjs");
You are referencing two different libraries, though different by one character. Use this:
const brain = require('brain.js');

npm ERR! npm v3.5.2
As discussed in the comments, this is an old version of NPM and the solution was to update to a newer version.

Is this a permissions issue? Or is there something wrong with the way npm is set up? Any help would be appreciated.

Try recreating package.json for that repo with npm init . command and go through all the steps.
Remember having correct repository link in the repository section.
I had the same problem but above helped.

Problem 1: The repo on your post does not exist.
You might've used the wrong repo url.
Use the correct repo url: https://github.com/akveo/ng2-smart-table
Problem 2: The repo does not have a version specified in the package.json
Just fork it and add a version in the package.json file.
Or, use the npm version,
npm install --save ng2-smart-table

npm install -g . doesn't copy, fails

The npm developer docs say to make sure your package installs globally before publishing by running npm install -g .. I'm trying to build an ES6 CLI package that can be installed and run globally, but after running Babel to transpile it (with the es2015 plugin), the global install on my machine fails.
I've created a simple demo ES6 project that reproduces the error. Cloning and running npm install -g . throws the error in the README:
$ npm install -g .

Am I doing something wrong? I've tried a few different commands, with both Babel and NPM, but ultimately nothing seems to get copied into /usr/local/lib/node_modules.
$ node -v

EDIT: The error appears to be the same with the latest node and v0.10.24, with and without sudo. The logfile says:

The "bin" property of the package.json points to an app.js file in es5/bin but there is no app.js file. You'll need to point it to the csp.js file:
package.json
"bin": {
"csp": "es5/bin/csp.js"
},

I don't understand why but I can't execute server. How can I fix it? Thanks in advance.

It seems node is installed with version node#v0.10.32
Anyhow, what really happens is that npm looks in your package.json file, and if you have something like
"scripts": { "start": "coffee server.coffee" } }
then it will do that. If npm can't find your start script, it will not work
try node start using
node <name of your node server>.js
and error seen in your angular-phonecat Try reinstalling it using npm command and try.
