npm安装报错

安装插件报错：

npm i vue-loader-plugin -S

npm ERR! cb() never called!

npm ERR! This is an error with npm itself. Please report this error at:

npm ERR! A complete log of this run can be found in:
npm ERR!     E:\Program Files\nodejs\node_cache\_logs\2020-03-20T02_49_18_413Z-debug.log

直接改成 

cnpm i vue-loader-plugin -S

就ok.  原因不清楚 npm 安装没 cnpm 安装好用
