节点 npm 本地安装覆盖全局安装
如果我在本地安装了节点模块（与我的节点应用程序位于同一文件夹中），它们是否会覆盖相同模块的全局安装？
If I have node modules installed locally (in the same folder as my node app) will they override global installations of the same modules?

是的。请参阅此处有关模块解析的文档。而且，需要明确的是，这里的“覆盖”仅意味着本地模块是将被解析到的模块。全局模块将保持不变，其他目录中的 Node.js 应用程序仍然能够使用全局模块。
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/).
Yes. See the documentation here 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.
