Node environment configuration

There are two main changes ：（ Assume node The installation directory is D:\nodejs）

1. Global module download installation directory ：

npm config set prefix “D:\nodejs\node_global”

npm config set cache “D:\nodejs\node_cache”

After modification , The downloaded module is automatically installed in D:\nodejs\node_global Under the node_modules In the catalogue

2. Modify environment variables

2.1) In user variables , find path, Delete npm Environment variable value at the end （ There are plenty of them npm/node_modules ending ）, add value ：D:\nodejs\node_global

2.2) In user variables , newly added NODE_PATH Variable , The value is ：D:\nodejs\node_global\node_modules

After modification ,node Can be loaded into the downloaded module

The above two steps , Especially the environment variables NODE_PATH Value , Finally, I want to write node_modules Catalog , otherwise , The corresponding package will not be loaded . You can enter commands npm install -g vue install vue modular , Then type the command node, And then you type in require('vue'), Return module information , Load succeeded , To configure ok; Or write a js Scripts like test.js, Content such as ： var vue = require('vue');console.info(vue); And then in cmd perform node test.js, Return module information , Load succeeded , To configure ok

3. Switch the mirror address （ Optional ）

download nrm package ：npm install -g nrm

Switch the image address to Taobao npm Mirror address ：nrm use taobao
