There are couple of ways to install node.js and npm in Windows.

  1. GUI (manual method)
  2. Using chocolatey (Powershell)

Please make a note, npm (node package manager) will auto install in windows 10 with node.js.

1:- How to install node js on Windows 10

Step1:- Download node js

Download Node.js software from nodejs.org website. The latest LTS version is node-v14.15.3. Package npm is in-built. You don’t need to install it separately. If you own an old version of windows, select 32-bit version of node.js installer. Otherwise, choose 64-bit in all other cases.

I will select 64-bit version.

Download-node-js

Step1.1

After download of node js completes. Visit your download directory.

Nodejs-latest-version

Step2:- Install Node.js and npm

Double click installer node-v14.15.3-x64.msi. This will start Node Js installation wizard.

Click Next

node.js-setup

Step2.1

Select “I accept the terms in the license Agreement” box. It confirms that you agree with node.js end user license agreement. Click Next

node-js-EULA

Step2.2

Select the destination folder for node.js installation. Default location of node.js is “C:\Program Files\nodejs\“. In case, you want to select a custom location. Click on change and browse for your preferred install location.

Select – Next.

Step2.3

Select node.js features. I will suggest you leave it default. Also, npm (node package manager) is part of features. So you don’t need to install it separately.

Space required to install these node js and npm features need 143MB capacity.

Following features will install by default –

  • Node.js runtime
  • Npm package manager
  • Online documentation shortcuts
  • Add to Path

Click Next

node-js-features

Step2.4

Choose an optional tool to compile native modules, if required. Some npm modules need to be compiled from C/C++. To install these modules, you will need python and Visual studio build tools.

Choose box “Automatically install the necessary tools option“. You can visit https://github.com/nodejs/node-gyp#on-windows to install it later manually. We will discuss the chocolatey software in the next section.

In my case, i have not selected this option.

Choose Next.

2:- How to install node js in Windows using chocolatey {Powershell}

There is one more way to install node.js and npm using chocolatey. It is a software management solution. You will need PowerShell to run these commands.

Follow these commands one by one –

Step1:- Open PowerShell as admin

Type PowerShell in search box and open it as run as administrator.

Step2:- Set Execution policy

The execution policy is “restricted” by default in PowerShell. This policy will not allow you to run scripts. So you need to change it to “AllSigned“. So that it allows to download and run chocolatey commands.

C:\> Set-ExecutionPolicy AllSigned
set-execution-policy-powershell

Step3:- Download and Install Chocolatey using PowerShell script

Copy and paste this script to download and install chocolatey software in Windows. It will install the latest version of the chocolatey package.

It also download 7-zip tool and install it prior to extraction. You can safely ignore warnings while installing chocolatey.

C:\> Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
install-chocolatey-using-powershell

If you get warning “Not setting tab completion: Profile file does not exist at <location>”. Make a folder on that location. it will help you to complete chocolatey commands using Tab. For example, I will make a folder in “C:\users\Dev\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1”.

Step4:- Install node.js using choco command

Run choco command to download and install node js and npm using PowerShell. You can use -Y option for the non-interactive run.

> choco install nodejs

Use –force option, in the case earlier node.js installation failed. This will install the latest node.js version available.

To install specific version, give details in command. For example, i have given version 12.10.0.

> choco install nodejs --version=12.10.0
install-nodejs-using-chocolatey-powershell

Step5:- Check node js and npm version

Check node js version

> node --version

Check npm version

> npm --version
check-node-and-npm-version

Step6 (optional):- Install angular CLI

This step is optional and only need to run, if you need angular CLI. NPM command will help to download and install angular package.

Open command prompt with “run as administrator” rights. Then run npm command to install angular/cli.

option i – to install package

-g option – for global in npm command.

> npm i -g @angular/cli
install-angular-cli

or use @version to install version, you need. For example 1.8.2

npm i -g @angular/cli@1.8.2

  1. Hi !
    This is a very interesting and well explained post !
    I followed what was shown but failed to update node and npm. I have a Window 10 with Linux and Ubuntu installed on it.
    I currently have version 3.10.10 of npm and 14.15.0 of node and when I try to update them I have this problem :

    npm ERR! node v14.15.0
    npm ERR! npm v3.10.10

    What could be the solution here? Thanks in advance.
    Thanks !

    1. Hi Josephine,

      Thanks and happy to know that you liked this article. I have few questions –
      1.) Are you trying to update npm v3.10.x to the latest? Have u tried removing this legacy version and then installing latest version fresh?
      2.) Looks like you are using WSL2. Can you please confirm ubuntu version? On which you are trying to upgrade NPM and node?

      I will try to replicate this issue in my PC, once you will reply and will try to solve it.

      Thanks
      Dev

      1. Yes I’m trying to update npm v3.10.x to the latest version. I tried removing npm but it doesn’t work and I get the same error message coming back (npm ERR! Linux 5.4.72-microsoft-standard-WSL2…).
        I’m using Ubuntu 20.04.1 LTS.
