Prerequisites

Node.js

Installing

Check your software for your operating system. You should install Node.js.

Linux

You should download binary archive from Node.js official site. To install Node.js, please follow the official instructions or the short guide below:

Create a directory nodejs in /usr/local/lib:

$ sudo mkdir /usr/local/lib/nodejs

You should pass to the directory where you downloaded the binary archive. I use nodejs version 12.16.3 distributive linux-x64. The command to unziping the binary archive to already created directory looks like:

$ sudo tar -xJvf node-v12.16.3-linux-x64.tar.xz -C /usr/local/lib/nodejs

Set the environment variable to use Node.js. Add lines below to the end in your ~/.profile file:

# Export Node.js to PATH
export PATH=/usr/local/lib/nodejs/node-v12.16.3-linux-x64/bin:$PATH

You should refresh your profile:

. ~/.profile

To check version of node enter the command $ node -v in terminal. The output of the command would be something like this:

$ node -v
v12.16.3

To check version of npm enter the command $ npm version in terminal. The output of the command would be something like this:

$ npm version
{
  npm: '6.14.4',
  ares: '1.16.0',
  brotli: '1.0.7',
  cldr: '36.0',
  http_parser: '2.9.3',
  icu: '65.1',
  llhttp: '2.0.4',
  modules: '72',
  napi: '5',
  nghttp2: '1.40.0',
  node: '12.16.3',
  openssl: '1.1.1g',
  tz: '2019c',
  unicode: '12.1',
  uv: '1.34.2',
  v8: '7.8.279.23-node.35',
  zlib: '1.2.11'
}

To check version of npx enter the command $ npx -v in terminal. The output of the command would be something like this:

$ npx -v
6.14.4

Windows

You should download Windows Installer from Node.js official site. To install Node.js start the installer and follow instructions.

To check version of node enter the command > node -v in command prompt. The output of the command would be something like this:

> node -v
v12.16.3

To check version of npm enter the command > npm version in command prompt. The output of the command would be something like this:

> npm version
{
  npm: '6.14.4',
  ares: '1.16.0',
  brotli: '1.0.7',
  cldr: '36.0',
  http_parser: '2.9.3',
  icu: '65.1',
  llhttp: '2.0.4',
  modules: '72',
  napi: '5',
  nghttp2: '1.40.0',

  unicode: '12.1',
  uv: '1.34.2',
  v8: '7.8.279.23-node.35',
  zlib: '1.2.11'
}

To check version of npx enter the command > npx -v in command prompt. The output of the command would be something like this:

> npx -v
6.14.4
