npm will create a node_modules directory in the directory where the local installation command is executed and install it in this directory. Only the js program in the directory where the command is executed or its subdirectory can access the partially installed package. npm list lists locally installed packages in the current directory.

Global installation

If you want to use the installed package anywhere, you need to add a global command -g## during installation. #

npm install xxxx -g

Globally installed packages are installed directly into the computer. You only need to install them once, and you can use this package anywhere on the computer in the future; npm list -g lists globally installed packages and also displays global installations. path of.
