[已解决] 关于 执行 NPM run watch-poll 后出现 95% emittingError: EIO: i/o error, close ？

环境:
windows 10
npm:6.1.0
目的:
运行 npm run watch-poll 执行 sass 预编译 CSS

步骤:

1. 安装 yarn install --no-bin-links 出现 save lock fild 字样，“成功”（问了好些人，给了这么一个说法：有时出现成功字样，但未必能完整下载整个 npm 包，通讯问题）。
   
2. 删除 package.json 四处 cross-env 依赖文件和 devDependencies 中的依赖 cross-env
   
3. 运行 npm run dev，未报错（但此时并未修改 resources/assets/sass/app.scss 文件)
   
4. 将 app.scss 文件清空，并引入 import "node_modules/bootstrap-sass/assets/stylesheets/bootstrap";，然后执行 npm run watch-poll 出现如下图所示错误
   
   
   以下为 package.json
   
   

找到 “类似” 情况，尝试了其解决方法仍未成功，望各路前辈指点思路

以下为完整报错文字
