nrm

一个帮助你管理npm镜像源的工具，助你省心切换镜像源。

安装

npm install nrm -g

基本命令

nrm -V 查看安装版本，也看查看是否安装成功

nrm -V

可能会报错

D:\nvm\v16.16.0\node_modules\nrm\cli.js:9
const open = require('open');
             ^

Error [ERR_REQUIRE_ESM]: require() of ES Module D:\nvm\v16.16.0\node_modules\nrm\node_modules\open\index.js from D:\nvm\v16.16.0\node_modules\nrm\cli.js not supported.
Instead change the require of index.js in D:\nvm\v16.16.0\node_modules\nrm\cli.js to a dynamic import() which is available in all CommonJS modules.
    at Object.<anonymous> (D:\nvm\v16.16.0\node_modules\nrm\cli.js:9:14) {
  code: 'ERR_REQUIRE_ESM'
}

解决办法： 命令行终端输入：npm i nrm -g open@8.4.2 --save，安装完成后再输入nrm -V就可显示版本号
