节点 npm 本地安装覆盖全局安装

Question

如果我在本地安装了节点模块（与我的节点应用程序在同一文件夹中），它们是否会覆盖相同模块的全局安装？

Answer 1

Yes. See the documentationhere on module resolution. And, just to be clear, "override" here simply means that the local module is the one that will be resolved to. The global module will be left untouched, and node.js apps in other directories will still be able to use the global module.

Edit: it would probably also help to better understand how the global installs with npm work. More info on that is [here](https://nodejs.org/en/blog/npm/npm-1-0-global-vs-local-installation/).
