Friends who have used gulp should know that some gulp plug-in Nodejs and NPM version number is required, such as:

Open a command-line window to execute NPM install-g NPM

Delete the three files in the Nodejs installation directory at the same time: because you already have: D:\nodejs\ in the system environment variable; If not removed, this version overrides the globally installed NPM and looks at the results if the three files were not deleted: Delete the three files and try again: (If your NPM global installation path is already configured in the system environment variable, here my global installation path can look at a blog post, Re-environment variable path added: D:\nodejs\npm_global_modules) If you have any other way, welcome to comment yo ~
