fix the error when options is {} or undefined, but the prefix is undefined

[sxzz]

Would you please provide a reproduction about this issue you fixed?

[crossskyLi]

import IconVue from '@element-plus/icons-vue' IconVue(App)

[sxzz]

Please upgrade to latest version. I can't reproduce it.

import { createApp } from 'vue'
import icons from '@element-plus/icons-vue/global'
import App from './App.vue'

const app = createApp(App) // or .use(icons)
icons(app)
app.mount('#app')

If you write code like this, won't you report errors?

So without minimum reproduction, I can't give you any help.

I mean, a real project.

I see you've fixed the situation I was trying to fix, at last few version you can close my request. Thank you.
