Answer 1

I tried to install npm using npm installbut it gives following warnings.

npm WARN saveError ENOENT: no such file or directory, open 'F:\ucsc\3rd year\Mobile Application Development\lec. notes\abc\package.json'
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN enoent ENOENT: no such file or directory, open 'F:\ucsc\3rd year\Mobile Application Development\lec. notes\abc\package.json'
