使用命令node-sass将npm install --save-dev node--sass@4.7.2安装到Windows7中时，出现上述错误。

有人可以帮我吗？预先谢谢你。

您可以尝试阅读NPM正在记录的错误消息：

npm ERR! 404 Not Found - GET https://registry.npmjs.org/node--sass - Notfound
npm ERR! 404
npm ERR! 404  'node--sass@4.7.2' is not in the npm registry.
               ^^^^^^^^^^

您正在尝试安装名为node--sass的软件包，该软件包在NPM中不存在，而不是所需的软件包node-sass，而确实在NPM中存在。
