How can I update npm on Windows?

Answer 1

This works fine for me

1. Run Command Prompt as Administrator

2. Navigate to the folder containing nodejs (eg. C:\Program Files\nodejs)

3. Run Powershell -ExecutionPolicy Unrestricted

4. Run npm-windows-upgrade

5. This will show list of versions available to install. Just select your desired version by moving up/down key & Press Enter.
   
   This'll update your npm
6. To check the current version of npm

   Run npm --version
