Answer 1

You need to update all of your globally installed NPM packages. Run this command from your console:

npm update -g

This command will update all the packages listed to the latest version (specified by the tag config).

It will also install missing packages.

When you specify the -g flag, this command will update globally installed packages. If no package name is specified, all packages in the specified location (global or local) will be updated.
