How can I update npm on Windows?

I tried this:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

...but it didn't work.

How do I do this on Windows?

Note: The question is specifically asking how to upgrade npm, not Node.js. If you want to update Node.js over a CLI on windows, I recommend running winget upgrade -q NodeJS or use chocolatey for that.

What method should I choose to update NPM?

• Node.js v16 or higher?
  • npm install -g npm
• Node.js v14 or below?
  • Consider updating to latest LTS release of Node.js
  • npm-windows-upgrade

Upgrade with npm-windows-upgrade

Run PowerShell as Administrator

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

Note: if you run the Node.js installer, it will replace the Node.js version.

• Upgrades npm in-place, where Node.js installed it.
• Does not modify the default path.
• Does not change the default global package location.
• Allows easy upgrades and downgrades and to install a specific version.
• A list of versions matched between NPM and Node.js (https://nodejs.org/en/download/releases/) - but you will need to download the Node.js installer and run that to update Node.js (https://nodejs.org/en/)

Upgrade with npm

npm install -g npm

Note: some users still report issues updating npm with npm, but I haven't had that experience with v16+.
