Answer 1

View npm config through npm config ls, check the registry

→ npm config ls
; cli configs
user-agent = "npm/2.14.2 node/v4.0.0 darwin x64"

; userconfig /Users/xxx/.npmrc
email = "[email protected]"
registry = "https://registry.npm.taobao.org/"

If you use third party registry like 'taobao.org' etc., you will absolutely get the 'Incorrect username or password' error tip.

Solution

Change back to use official registry npmjs.org temporarily:

npm config set registry https://registry.npmjs.org/
