通过import的scss文件间接引入node_modules中的scss文件报错

[imageslr]

问题描述
在/variables.scss文件中引入taro-ui的默认变量包，然后在/app.scss中引入/variables.scss时报错：
message: 'File to import not found or unreadable: ~taro-ui/dist/style/index.scss.'

复现步骤
[复现问题的步骤]

1. 新建文件/variables.scss，内容仅有一行@import "~taro-ui/dist/style/index.scss";
2. /app.scss中仅有一行@import "./styles/variables.scss";
3. /app.js中import "./app.scss";
4. 编译文件

期望行为
编译成功

补充信息
根据报错信息'File to import not found or unreadable: ~taro-ui/dist/style/index.scss.'可以看到是在文件名index.scss后面多加了一个点。

直接导入node_modules中的scss就不会有此问题：

• 直接在/app.scss中@import "~taro-ui/dist/style/index.scss";，问题
• 在自定义组件的scss文件中@import "~taro-ui/dist/style/index.scss";亦无此问题

@imageslr 目前解决方法有两个：

1. 在 js 中用 import '~taro-ui/dist/style/index.scss' 引入
2. 增加 sass 的 importer 配置，可参考 https://github.com/js-newbee/taro-yanxuan/blob/master/config/index.js

[imageslr]

谢谢！ @js-newbee 明早看看

[imageslr]

第二个方法很简单，已经解决，多谢！

大神出手完美解决问题 !
问题描述大概如下:

1. 通过这个链接生成新的theme https://nervjs.github.io/taro-ui-theme-preview/
2. 生成的新的主题存在一个目录里,比如 assets
3. 然后按照这个方法, 在APP.scss里面引入进
   
4. 会报错

js-newbee大神的方法真的很好

今日测试，不行了，依然会提示缺少npm包@gzcrm/XXX/theme，开始安装...

[suneai]

./node_modules/taro-ui/dist/weapp/index.js
Module not found: Can't resolve './style/index.scss'
我的报这个错误，就算是把modules全部删除了重新安装依赖也还是不行
但是运行yarn dev:h5的时候没有问题yarn dev:weapp不行

您好，请问现在项目直接从taro1升级到3.0版本，plugins配置的写法完全变了，该如何配置sass中的引入文件别名配置呢
