常见问题处理

vue3 启动时白屏

在启动vue3版本（不刷新浏览器）时，会出现白屏的现象。并且控制台报异常：

如果直接打开URL，也会得到504错误，比如:
https://localhost:1803/app/node_modules/.vite/deps/pusher-js.js?v=601736dc

但是去掉版本信息后，又完全正常:
https://ocalhost:1803/app/node_modules/.vite/deps/pusher-js.js

这时可以使用：

npm rebuild

或者

node ./node_modules/esbuild/install.js

详细原因可以查看：https://github.com/vitejs/vite/discussions/8146

修复方法：

• 修改package.json文件中node-sass版本：

"node-sass": "^6.0.1",

• 清理node缓存，重新安装：

npm cache clean --force
npm i
