Vue中使用/deep/bug

Question

我在vue-lic3中使用了SCSS，但是有一个奇怪的bug，使用/deep/会报错，我不想看到。

代码运行环境 vue-cli3 + vant + scss

css

/deep/ .van-tabs__content.van-tabs__content--animated,
  .van-tabs--line,
  .van-pull-refresh,
  .van-pull-refresh__track {
    height: 100%;
  }

vue.config.js

css: {
    loaderOptions: {
      sass: {
        data: `@import "~@/style/module.scss";`
      }
    }
  },

错误

Failed to compile with 1 errors                                                                                                                                                                           14:14:46

Answer 1

对我来说 /deep/ 不会编译。

我用::v-deep：

.scoped-element {
    color:white;

    ::v-deep .child-of-scoped-element {
        color: black;
    }
}

或者

.scoped-element::v-deep.child-of-scoped-element {
    color: black;
}

在我的项目中，我使用下一个语法.class__name { /deep/ { .class_i_want_to_change {}}}，它工作正常。你试过了吗？
