nrm报错 code: ‘ERR_INVALID_ARG_TYPE‘解决方法

命令npm install nrm -g安装，nrm 1.2.1报错：

[TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined

] {
  code: ERR_INVALID_ARG_TYPE
}

找到nrm目录(错误第四行) 打开cli.js 第17行修改成

//const NRMRC = path.join(process.env.HOME, .nrmrc); (删除)
const NRMRC = path.join(process.env[(process.platform == win32) ? USERPROFILE : HOME], .nrmrc);

保存后重新打开命令行，可正常运行nrm ls命令

C:Windowssystem32>nrm ls
