nodejs|npm加速安装node_module模块

前言

npm默认源为https://registry.npmjs.org/，但是下载速度慢。下面介绍一下如何加速下载模块。

1.临时设置

npm i express --registry https://registry.npm.taobao.org

2.永久设置

2.1 npm config命令

设置：

npm config set registry https://registry.npm.taobao.org

查看：

npm config get registry

2.2 npmrc文件

编辑 ~/.npmrc 加入下面内容(上面的命令也是设置该文件)

registry = https://registry.npm.taobao.org

2.3 nrm命令管理源

npm i nrm -g --registry https://registry.npm.taobao.org

查看源

nrm ls

* npm -------- https://registry.npmjs.org/
  yarn ------- https://registry.yarnpkg.com/
  cnpm ------- http://r.cnpmjs.org/
  taobao ----- https://registry.npm.taobao.org/
  nj --------- https://registry.nodejitsu.com/
  npmMirror -- https://skimdb.npmjs.com/registry/
  edunpm ----- http://registry.enpmjs.org/

测试源速度

nrm test 

* npm ---- 1069ms
  yarn --- 2328ms
  cnpm --- 689ms
  taobao - 103ms
  nj ----- Fetch Error
  npmMirror  935ms
