这些报错着实看着头大，除去哪些gyp开头的先别看，但首先要冷静，摘取一下关键信息

Binary has a problem: Error: The module '\\?\D:\Googledownload\win32-x64-93_binding.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 93. This version of Node.js requires
NODE_MODULE_VERSION 72. 

问题似乎是这个啥啥啥module的版本有问题，又去查了一下nodejs和NODE_MODULE_VERSION版本对应，发现没啥用
但93和72这个应该是个问题切入点，直接去搜了win32-x64-93_binding.node这个文件，发现和就是node-sass模块文件！
看到这里心里大概就明白了，于是去查看各版本的node-sass，链接
项目中用的node-sass是4.14.1，于是进入这里看看

发现在这个版本下的win-x64-xx是没有93后缀的，所有问题出在这里，vue在install找的文件错了

然后把win32-x64-72_binding.node下载下来，替换到报错信息下的那个文件目录，比如我的是：

再次npm install就行

补充背景信息，这个错可能花了两三天才解决，期间一直在重装nodejs和node-sass，网上的解决办法大多都是要你重装这两个东西，大概也猜的出来可能是版本问题，可是在接连重装好多版本后都不能解决
我的猜测：可能是在这个项目第一次运行时，win32-x64-93_binding.node就和那个版本的node-sass绑定了，是一一对应的关系；在后续的卸载再重装node-sass时，这个文件没有手动删除，与后续的nodejs或者node-sass环境存在冲突，所以一直会报sass相关错误，但重装也不能解决的原因
教训：仔仔细细看报错原因才是正确的，一股脑地去查csdn行不通
