在uni-app vue3项目中，即使页面未添加scoped样式，仍会默认开启scoped效果，影响全局样式应用。通过深入研究，我们发现这是uni-app的默认设置，下面分享具体解决方案。

测试代码

<template>
  <view class="page">
    <view class="hero">
      <text class="eyebrow">Main packagetext>
      <text class="title">Rattail array helperstext>
      <text class="desc">
        This page lives in the main package and imports functions from rattail.
      text>
    view>    <view class="card">
      <text class="label">sourcetext>
      <text class="code">{{ sourceText }}text>
    view>    <button class="button" @click="goSubPackage">
      Open sub package rattail demo
    button>
  view>
template><script setup>
import { computed } from 'vue'
import { isString } from 'rattail'const numbers = [1, 2, 2, 3, 4, 4, 5, 6]const sourceText = computed(() => isString(numbers) ? 'A string' : 'Not a string')function goSubPackage() {
  uni.navigateTo({
    url: '/pages/sub/rattail/index',
  })
}
