TypeError [ERR_INVALID_ARG_TYPE]:The “path“ argument must be of type string. Received type undefined_typeerror [err_invalid_arg_type]: the "path" argum

一、npm run build 发生错误，代码如下，对号入座

> node build/build.js
 
- building for production...path.js:39
    throw new ERR_INVALID_ARG_TYPE('path', 'string', path);
    ^

二、网上查寻了很多，有不少关于版本的问题，我这里遇到的是“大白菜” 的问题。是在增加多网页设计时把内容填写错误导致。
