Build failed with error code: 1在 node scripts/install.js 之后发现这么一句话
Cannot download "https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-51_binding.node":
在网上下载，如果报错的版本和我的一样，可以用我下载好的文件 点击下载
下载完了之后把它注册成全局环境变量，两种方式：
第一种：直接右键我的电脑--》属性--》高级系统设置--》环境变量--》添加
第二种：set XXX=文件路经--》set SASS_BINARY_PATH=F:wwtoolsnode-sasswin32-x64-46_binding.node
查看环境是否合适：echo %SASS_BINARY_PATH%
如果打印出来您配置好的文件地址那就ok了，
最后再来试试安装：npm i -g node-sass
如果错误是有关 Python , 那就装Python 就能解决。
