NPM 在当前目录外安装包 [英] NPM Installs Package Outside Current Directory

问题描述

我尝试从/home/iwan/my-project 目录中使用 npm 安装 express 包:

I try to install express package using npm from inside /home/iwan/my-project directory:

npm install express

express@3.3.7 ../node_modules/express
├── methods@0.0.1
├── cookie-signature@1.0.1
├── range-parser@0.0.4
├── fresh@0.2.0
├── buffer-crc32@0.2.1
├── cookie@0.1.0
├── debug@0.7.2
├── send@0.1.4 (mime@1.2.11)
└── commander@1.2.0 (keypress@0.1.0)

奇怪的是 npm 没有在当前目录(/home/iwan/my-project/node_modules/express)中安装 express 包，而是在/home/iwan/node_modules/express 中.

The strange thing is npm doesn't install express package in current dir (/home/iwan/my-project/node_modules/express), but in /home/iwan/node_modules/express.

我错过了什么吗?

推荐答案

如果 node_modules 目录在您当前目录中不存在，NPM 将在更高的目录中寻找它，直到找到它.因此，如果父目录有一个 node_modules 目录，NPM 将假定它是安装模块的位置.

If the node_modules directory doesn't exist in your current directory, NPM will look for it in the higher directories until it finds it. So, if the parent directory has a node_modules directory, NPM will assume that's where it is to install modules.

解决这个问题的一个快速方法是创建一个空的 node_modules 目录，您希望在其中放置模块.

A quick way around this is to create an empty node_modules directory where you want the modules to be placed.
