Nodejs NPM Install the difference between global and local installation _node.js

NPM's package installation is divided into local installation (locals), global installation (globally), and from the command line, the difference is only G, for example:

Copy Code code as follows:

NPM Install Grunt # Local Installation
NPM install-g GRUNT-CLI # Global Installation


explained separately below.

1. When npm install XXX-G, the module will be downloaded and installed into the global catalog.

The global catalog is set by the NPM config set prefix directory path.

Obtain the current set of directories through the NPM config get prefix.

2. NPM Install xxx is the download module to the directory where the current command line resides.

For example:

Copy Code code as follows:
C:\123>NPM Install XXX

will be installed to
Copy Code code as follows:
C:\123\node_modules\xxx

This approach is obviously not good, so generally use the global installation of a unified installation of a directory, so that both convenient management, clear structure can be reused.
