node.js 模块路径 [英] node.js modules path

问题描述

我意识到，当我对 node.js 模块(带有 -g 标志)进行全局安装时，除非我写了整个路径，否则节点无法使用该模块.

I realised that when I did a global installation of a node.js module (with the -g flag) node couldn't use that module unless I wrote the entire path.

我的意思是，如果模块已全局安装，这将不起作用:

I mean, this doesn't work if the module has been globally installed:

cheerio = require('cheerio'),

我必须这样写:

cheerio = require('/usr/lib/node_modules/cheerio'),

我怎么能告诉节点它必须在正确的路径中寻找模块?

How can I say to node that it has to look for the modules in the right path?

谢谢.

推荐答案

一般来说，我建议让 npm 为您提供路径并按上述方式设置:

In general, I would suggest letting npm give you the path and set that as mentioned above:

$ echo 'export NODE_PATH="'$(npm root -g)'"' >> ~/.bash_profile && . ~/.bash_profile
