Node 版本升级后 vue2 项目启动错误 (node-sass 与 sass-loader)
前言
开始使用低于 vue-cli3 创建的项目，在更新node 到 12.x 后，项目运行不起来了
问题描述
node 版本升级后旧的 vue 项目启动报错
- 错误类型1
node Sass could not find a binding for your current environment: Windows 64-bit with node.js 12.x
Found bindings for the following environments:
– Windows 64-bit with node.js 8.x
– Windows 64-bit with node.js 12.x
This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to download the binding for your current environment.
尝试执行命令 npm rebuild node-sass，，提示安装 Python 环境
Error: Can’t find Python executable “python”, you can set the PYTHON env variable.
- 错误类型2

npm ERR! errno 1

内容分析
通过错误信息提示以及网络查找，很容易就发现产生的原因：高版本的 NodeJS 对 node-sass 不是很友好（兼容问题）
下面是 node 与 sass-node 的版本对照
| NodeJS | Supported node-sass version | Node Module |
|---|---|---|
| Node 17 | 7.0+ | 102 |
| Node 16 | 6.0+ | 93 |
| Node 15 | 5.0+, <7.0 | 88 |
| Node 14 | 4.14+ | 83 |
| Node 13 | 4.13+, <5.0 | 79 |
| Node 12 | 4.12+ | 72 |
| Node 11 | 4.10+, <5.0 | 67 |
| Node 10 | 4.9+, <6.0 | 64 |
| Node 8 | 4.5.3+, <5.0 | 57 |
| Node <8 | <5.0 | <57 |
解决方法
重新安装对应兼容版本的 node-sass 即可，注意别忘了 sass-loader
npm install node-sass@6.0.1 sass-loader@10.2.0
