Error: pngquant failed to build, make sure that libpng-dev is installed

遇到了一个很难搞的报错

新同事遇到的，最开始的体现是这样的

看到这个报错是很懵的，进入到对应的依赖目录下，发现pngquant.exe不存在

认为是依赖装得有问题，各种卸载重装，重新配置淘宝镜像，遇到新报错

关键提示：pngquant failed to build, make sure that libpng-dev is installed
我是很懵的，搜了一圈也没找到类似的问题，查到libpng-dev是在linux下安装的

从pngquant入手，这种情况其实就是系统环境缺了一个 dll文件, 导致 去安装 pngquant插件的时候报错

解决方法：
-> 前往 https://pngquant.org/ 下载pngquant库

->解压压缩包至C:\Windows\System32目录下

->管理员身份运行pngquant.exe

再安装就不会报错了

PS:以管理员运行pngquant.exe的时候，可能会遇到缺少vcruntime140.dll库的提示
