Verify Node.js Installation

Reinstall Node.js

If the above steps don’t work, consider reinstalling Node.js:

• Go to Programs > Programs and Features.
• Find and uninstall Node.js.

Reinstall Node.js

• Download the latest Node.js installer from the official Node.js website.
• Run the installer and ensure that the option to add Node.js to the PATH is checked.

Step 1:

Open the Environment Variables option in your Control Panel. (Go to Control Panel -> System and Security ->System -> Advanced System Settings-> Environment Variables ->User Variables or System Variables.)

Step 2:

Step 3:

Restart the command prompt again and now verify by typing node-v in the command prompt. It will now display the version of the node which you've installed from the internet .
