Local Npm module "grunt-contrib-copy" not found. Is it installed?
Local Npm module "grunt-contrib-uglify" not found. Is it installed?
Local Npm module "grunt-contrib-jshint" not found. Is it installed?

Warning: Task "copy:vendor" not found. Use --force to continue.
Aborted due to warnings.
I have tried "npm install", "npm install grunt --save-dev", "grunt init:node". to fix the problem; it didn't work. Can anyone help? Thanks.
