Error: The command "npm install" exited with code 1

Add environment variable, right click this PC

• Go to Properties
• Go to Advance tab
• Click environment variable
• In User variable section click new, Enter variable name "Path" and value C:\Users\User\AppData\Roaming\npm
• One more - In User variable section click new, Enter variable name "Path" and value C:\Program Files\nodejs

If Path variable already there, then you can edit that variable add new path(value) by ; separation.
