Node Sass could not find a binding for your current environment: 问题

接手项目时要求环境为node 14,但是在运行编译的时候控制台报错

Module Error (from ./node_modules/sass-loader/dist/cjs.js):
Missing binding /Users/leon/Documents/projects/zzz/uni-mobile-protection/node_modules/node-sass/vendor/darwin-x64-72/binding.node
Node Sass could not find a binding for your current environment: OS X 64-bit with Node.js 12.x
Found bindings for the following environments:
   - Windows 64-bit with Node.js 14.x
   - OS X 64-bit with Node.js 14.x

于是执行npm rebuild node-sass,理论上会重新pull node-sass中缺少的文件 即为darwin-x64-72/binding.node
但是重新运行编译还是报相同的错误
仔细查看npm rebuild node-sass的结果

leon@leondeMac-mini uni-mobile-protectionx % npm rebuild node-sass

> node-sass@5.0.0 install /Users/leon/Documents/projects/zzz/uni-mobile-protectionx/node_modules/node-sass
> node scripts/install.js

node-sass build Binary found at /Users/leon/Documents/projects/zzz/uni-mobile-protectionx/node_modules/node-sass/vendor/darwin-x64-83/binding.node

> node-sass@5.0.0 postinstall /Users/leon/Documents/projects/zzz/uni-mobile-protectionx/node_modules/node-sass
> node scripts/build.js

Binary found at /Users/leon/Documents/projects/zzz/uni-mobile-protectionx/node_modules/node-sass/vendor/darwin-x64-83/binding.node
Testing binary
Binary is fine
node-sass@5.0.0 /Users/leon/Documents/projects/zzz/uni-mobile-protectionx/node_modules/node-sass

npm自动安装了darwin-x64-83/binding.node，因为当前运行的node环境是node14
报错提示缺少darwin-x64-72/binding.node，根据提示和node-sass文档可知72对应的node版本为node12
所以用nvm切换node版本为node 12, npm cache clean --force清除一下缓存，否则rebuild的时候npm很可能用了本地缓存的node-sass文件（吃亏了md）
清除缓存后npm rebuild node-sass 执行成功 控制台提示下载的是darwin-x64-72/binding.node
然后切回之前项目要求的node 14版本 编译执行，成功运行
