nrm

介绍

nrm(npm registry manager)是npm的镜像源管理工具，有时候国外资源太慢，使用这个就可以快速地在 npm源间切换

安装

npm install -g nrm

安装报错

internal/validators.js:124
    throw new ERR_INVALID_ARG_TYPE(name, 'string', value);
    ^

}

1. 找到D:\nvm\v14.15.4\node_modules\nrm\cli.js这个文件
2. 删除17行const NRMRC = path.join(process.env.HOME, '.nrmrc');
3. 替换17行const NRMRC = path.join(process.env[(process.platform == 'win32') ? 'USERPROFILE' : 'HOME'], '.nrmrc');

常用命令
