我是一个新成员，加入了一个使用 yarn 而不是 npm 的 Web 项目。而且还有一些额外的库和配置，这些我以前没有用过。
问题在于，我一直在尝试使用 yarn 在我的机器上安装 node-sass，但指令给出了一个错误。
我尝试安装多个版本的 NodeJS，安装了 yarn，Python 2.7（包括配置 Windows 环境变量）。
此外，我还安装了 windows-build-tools：
npm install --global --production windows-build-tools
也安装了 node-gyp：
npm install --global node-gyp
我只安装了 Visual Studio 2019，以及 .Net Framework 4.5.1
如果有人知道为什么会出现这个问题，将不胜感激！
带有错误的日志：
yarn add node-sass
yarn add v1.22.5
