项目场景：

在测试使用 uniapp-uview-ui 的时候,测试运行报错

问题描述

在网上找解决方案,大家的方案都不太适用
尝试过的方案

• 检查 uview-ui 的所在路径和引入中写的是否一致
• 重启 HX
• 确保安装了 scss/sass 插件
• 在根目录下 uni.scss 文件中引入 theme.scss
• 确保在根目录下 App.vue 文件中添加 lang=“scss” 和 index.scss
• 在引入全局样式的时候Sass加载不到 (npm init / npm install sass-resources-loader --save-dev)

原因分析：

后来,发现自己引入的语句写错了,真的是很无厘头,在引入的时候自动补全没看清,所以特此记录

在引入 uView 的全局 SCSS 主题文件的时候,在项目根目录的 uni.scss中引入此文件.

错误引入

/** uni.scss 错误引入*/
@import url("uview-ui/theme.scss");

正确引入

/** uni.scss 错误引入*/
@import "uview-ui/theme.scss";
