npm 常用命令和 nrm 管理工具

1. 常用命令

查看 npm 全局包

~ npm list -g
/usr/local/lib
├── corepack@0.10.0
├── create-react-app@5.0.1
├── nodemon@2.0.20
├── npm@8.5.0
├── nrm@1.2.5
├── open@8.4.2
└── pm2@5.2.2

查看 npm 源

npm config get registry
# 或
npm get registry

设置 npm 源

# 淘宝镜像源
npm config set registry http://registry.npm.taobao.org
# npm 官方源
npm config set registry https://registry.npmjs.org

这样切换很不方便，用 nrm 做管理

2. 用 nrm 做源管理

2.1 安装

sudo npm install nrm -g

(base) ➜  ~ nrm ls
/usr/local/lib/node_modules/nrm/cli.js:9
const open = require('open');
             ^

Error [ERR_REQUIRE_ESM]: require() of ES Module /usr/local/lib/node_modules/nrm/node_modules/open/index.js from /usr/local/lib/node_modules/nrm/cli.js not supported.
Instead change the require of index.js in /usr/local/lib/node_modules/nrm/cli.js to a dynamic import() which is available in all CommonJS modules.
    at Object.<anonymous> (/usr/local/lib/node_modules/nrm/cli.js:9:14) {
  code: 'ERR_REQUIRE_ESM'
}

发现报错，原因是引用的 open 包在 v9.x 之后改成 Native ESM，不再支持 require 引入方式。

Warning: This package is native ESM and no longer provides a CommonJS export. If your project uses CommonJS, you will have to convert to ESM or use the dynamic import() function. Please don't open issues for questions regarding CommonJS / ESM.

解决方案：指定低版本

sudo npm install nrm open@8.4.2 -g

2.2 使用

1. 查看源列表

(base) ➜  ~ nrm ls

  npm ---------- https://registry.npmjs.org/
  yarn --------- https://registry.yarnpkg.com/
  tencent ------ https://mirrors.cloud.tencent.com/npm/
  cnpm --------- https://r.cnpmjs.org/
  taobao ------- https://registry.npmmirror.com/
  npmMirror ---- https://skimdb.npmjs.com/registry/

2. 切换源

(base) ➜  ~ nrm use taobao


   Registry has been set to: https://registry.npmmirror.com/

3. 添加一个源

(base) ➜  ~ nrm add person http://xxx:4873/

    add registry person success

4. 删除

(base) ➜  ~ nrm del person

    delete registry person success

5. 测速

(base) ➜  ~ nrm test

* npm ------ 778ms
  yarn ----- 842ms
  tencent -- 1455ms
  cnpm ----- 1101ms
  taobao --- 179ms
  npmMirror - 5451ms
