Please either use yarn for package management or run npm install until it gets it right. There are a lot of problems with npm on windows, but there is nothing one can do except retry.

Thanks for your reply. Yarn is the very package management tool I am using. And I tried yarn install, all is updated.
However when I tried npm install, it really works. Problem solved. Thanks!

Wow, it's the first time this happens. Ok, so yarn is broken also on windows :(
