Nodejs prompt ' xxx ' is not a workaround for internal or external commands

This article describes the node. JS Package Management tool after the NPM installation module, unable to execute commands through the command line, prompting ' xxx ' is not a workaround for internal or external commands, to the required small partner reference.  

Typically this problem occurs because of a problem with the NPM installation, and the Global module catalog is not added to the system environment variable.

The Windows user checks to see if the directory under NPM is added to the system variable path, and if it does not exist, it needs to be added manually, as we paste the value of the path variable in the user variable into the system variable path, and the CMD console will need to be restarted after it is added.

NPM directory can be found using NPM command: NPM config get prefix

Well, the problem solved it, is not super simple and practical, I hope this article can help you.
