How can I update npm on Windows?

Answer 1

In my case, I discovered that I had two copies of Node.js installed. One under "C:\Program Files\nodejs" and another under "C:\Program Files (x86)\nodejs".

Answer 2

For what it's worth, I had to combine several answers...

1. Uninstall Node.js in control panel Add/remove programs.
2. Delete directories, both C:\Program Files (x86)\nodejs\ and C:\Program Files\nodejs\ if they exist.
3. Install the latest version, http://nodejs.org/download/

Answer 3

For NodeJS

Download required node version msi from here and install

for Npm

Run PowerShell as Administrator

Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
npm install -g npm-windows-upgrade
npm-windows-upgrade

Answer 4

You can use these commands:

npm cache clean
npm update -g [package....]

If you are upgrading from a previous version of node, then you will want to update all existing global packages. You can also specify the package name to be updated.

Answer 5

This is the new best way to upgrade npm on Windows.

Run PowerShell as Administrator

Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
npm install -g npm-windows-upgrade
npm-windows-upgrade

Note: Do not run npm i -g npm. Instead use npm-windows-upgrade to update npm going forward. Also if you run the NodeJS installer, it will replace the node version.

• Upgrades npm in-place, where node installed it.
• Easy updating, update to the latest by running npm-windows-upgrade -p -v latest.
• Does not modify the default path.
• Does not change the default global package location.
• Allows easy upgrades and downgrades.
• Officially recommended by the NPM team.
• A list of versions matched between NPM and NODE (https://nodejs.org/en/download/releases/) - but you will need to download NODE INSTALLER and run that to update node (https://nodejs.org/en/)

Answer 6

Open PowerShell as administrator.

To install a first time you can use this small script to download the latest msi and run it

$nodeLatest=((curl https://nodejs.org/download/release/latest/).Content | findstr x64.msi) -replace "<(.*?)>", "" -replace "\s+.+", "";
wget "https://nodejs.org/download/release/latest/$nodeLatest" -OutFile (join-path $env:TEMP node.msi); Start-Process (join-path $env:TEMP node.msi)

On future upgrades you can download just node.exe and update npm with

wget https://nodejs.org/download/release/latest/win-x64/node.exe -OutFile 'C:\Program Files\nodejs\node.exe'
npm i -g npm

You should now have the latest node and npm.

I went a little further and decided to implement a nvm for Windows.

Install-Module -Name power-nvm

nvm install latest
nvm default latest
