## 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：
|
||
|
||
```shell
|
||
npm rebuild
|
||
```
|
||
或者
|
||
|
||
```shell
|
||
node ./node_modules/esbuild/install.js
|
||
```
|
||

修复方法：
|
||
|
||
* 修改package.json文件中node-sass版本：
|
||
|
||
```javascript
|
||
|
||
"node-sass": "^6.0.1",
|
||
```
|
||
|
||
* 清理node缓存，重新安装：
|
||
|
||
```shell
|
||
npm cache clean --force
|
||
npm i
|
||
|
||
```
