Error in npm install while installing vendor files please help

pi@raspberrypi:~/MagicMirror $ npm install npm WARN deprecated time-grunt@2.0.0: Deprecated because Grunt is practically unmaintained. Move on to something better. This package will continue to work with Grunt v1, but it will not receive any updates. npm WARN deprecated @types/vfile-message@2.0.0: This is a stub types definition. vfile-message provides its own type definitions, so you do not need this installed.
