1、关于vue启动项目时报错
报错代码如下:
npm run dev
> hello-vue@1.0.0 dev F:\IDEA\Vue\vue_project\hello-vue
> webpack-dev-server --inline --progress --config build/webpack.dev.conf.js
18% building modules 69/75 modules 6 active ...Vue\vue_project\hello-vue\src\App.vue{ parser: "babylon" } is deprecated; we now treat it as { parser: "babel" }.

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 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大致的意思是node-sass和node-loader的问题，首先按照提示npm rebuild node-sass进行试着解决问题，但是中途这个node-sass要从GitHub上下载，出现几次网络问题，不能下载。
2、解决过程
2.1、看到网上说是node-loader的版本太高的原因
首先去vue项目下的
package.json中将node-lodaer的版本修改了下“sass-loader”: “^7.3.1”,
然后执行
npm install
然后重新打包项目运行
npm run dev
但是依旧报错
ERROR Failed to compile with 1 errors 5:43:54 ├F10: PM┤ error in ./src/views/Login.vue Module build failed: Error: Missing binding F:\IDEA\Vue\vue_project\hello-vue\node_modules\node-sass\vendor\win32-x64-72\binding.node Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 12.x说明安装的node-sass并没有安装在当前环境下，但是我去node-modules下的确看到了node-sass模块。令我百思不得其解。
2.2 实际解决方案
首先执行以下安装命令
npm install sass-loader@7.3.1 –save-dev
这样会将会安装
sass-loader@7.3.1并且将其添加到dev打包的环境下，这样才不会出现上面的在当前环境下找不到sass-loader（但是其实已经安装了），而且这里的sass-loader版本不能太高。再次执行
npm run dev
项目完美启动，没有报错。
