报错背景：

使用的Nodejs为v14.3.0版本与要安装的cnpm版本不符

报错原因：

关键看这句

Unsupported engine for cnpm@9.4.0: wanted: {"node":">= 14.18.0"} (current: {"node":"14.3.0","npm":"6.14.5"})

安装cnpm9.4.0版本需要nodejs版本>= 14.18.0，我的为v14.3.0版本，所以报错。

解决办法：

解决方法一：

将Nodejs卸载重新安装最新版本v18.19.0

再次执行npm install cnpm -g命令，安装成功！

解决方法二：

安装cnpm时指定较低的版本安装：

npm install -g cnpm@6.1.0
