解决方法：
1.在node官网下载node二进制文件包
2. 将下载好的二进制文件(*.zip)解压到对应的node版本包管理下（笔者的是在nvm包下，具体情况由安装情况决定），然后将解压的文件夹名字改成对应的版本好，如 v12.11.1

3.打开命令控制台，输入nvm use 最新版本号，即可使用最新的node版本了。

4.查看自己的cnpm，nrm是否能用，如果不能用，执行如下指令：
安装cnpm：
npm install -g cnpm –registry=https://registry.npm.taobao.org
或者： npm install -g cnpm –registry=http://r.cnpmjs.org

安装nrm：
cnpm install nrm -g 或者 npm install nrm -g
