cnpm 查看版本号 cnpm -v时报以下错误

查了一下，是因为npm的版本和cnpm版本不兼容导致的， cnpm@9.2.0 需要node版本>= 14.18.0，因此解决方案为降低cnpm版本

1. 降低版本前需要将原来装有的cnpm卸载

npm uninstall cnpm

2. 通过报错信息，可以知道当前cnpm安装的路径为D:\nvm\v14.17.2\node_modules

打开这个路径，把里面对应的cnpm相关文件删掉

3. 重新指定个低版本安装 例如 cnpm@6.0.0

npm install -g cnpm@6.0.0 --registry=https://registry.npm.taobao.org

4. 安装成功后，重新查看一下cnpm -v，发现成功了
