error D:\xxx\xxx\node_modules\node-sass: Command failed.
導言：運行老項目的時候經常遇到node-sass安裝不下來的問題，百度搜索更是千篇一律的鏡像原因，當然鏡像問題原因是更多人可能遇到的問題，比較少見的一種是運行老項目時，node版本比較低，導致node-sass安裝不了
提示node-sass安裝異常我遇到過兩種情況，一種是安裝依賴時需要node-sass，報錯一般是↓↓↓

一種是依賴安裝成功，但跑項目時因為部分依賴依賴了node-sass導致運行不成功，異常一般是↓↓↓
internal/modules/cjs/loader.js:717
return process.dlopen(module, path.toNamespacedPath(filename));

出現這種情況一般都是node-sass版本和node版本不對應，拿以上錯誤舉例
This version of Node.js requires NODE_MODULE_VERSION 64.
這句話的意思是：此版本的Node.js需要使用64版本的node-sass
可以去GitHub找到node-sass的對應版本：
https://github.com/sass/node-sass/releases
比如說我當前使用的node版本是10.14.1，則找到對應系統的對應node版本
下載對應系統對應node版本所需的node-sass
下載后放到本地磁盤，比如D盤
如果是安裝依賴時出了錯，則建議先把之前安裝的node_modules刪掉，然后設置node-sass路徑↓↓↓
// 刪除node_modules建議用命令行，更快！！
rmdir /s node_modules
// set SASS_BINARY_PATH=node-sass所在的路徑
set SASS_BINARY_PATH=D:/nodesass/win32-x64-64_binding.node
設置好node-sass路徑好正常安裝依賴即可
npm i 或 yarn
如果安裝依賴成功，但運行時出了node-sass的錯，則直接設置node-sass路徑然后運行↓↓↓
// set SASS_BINARY_PATH=node-sass所在的路徑
set SASS_BINARY_PATH=D:/nodesass/win32-x64-64_binding.node
npm run dev 或 yarn dev
注意：如果你通過以上方法成功安裝了依賴並成功運行了，但是，你在同時維護幾個不同node版本的項目，需要切換不同版本的node-sass和node，則建議切換項目后再設置一下node-sass路徑。
【補充】mac M1 pro node-sass 安裝失敗解決方法
說明：經過嘗試，發現 node-sass 好像不兼容 m1 ，所以建議將 node-sass 替換為 sass
- 刪除package.json 中的 node-sass 和 sass-loader
- 刪除 yarn.log !!!!!! (特別重要)
- 刪除 node_modules，終端指令 rm -rf node_modules
- node 版本切換為 14+
- 安裝 sass， yarn add -D sass 或 npm install --save-dev sass
- 安裝依賴 yarn
