Answer 1

Is this git? This is the node.js package management library npm. Some plug-ins need to be updated before installing gulp

Answer 2

You can try NODE’s own node command terminal for installation
The environment may be different if you use git bash

Answer 3

After I copied the node_modules folder to the Git installation directory today, it became normal. But I have never done this before, and it works. What is going on?
