I used SCSS in vue-lic3, but there was a strange bug, using / deep / will report errors, I don't want to see it.

Code Running Environment 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";`
      }
    }
  },

error

In my project I use next syntax .class__name { /deep/ { .class_i_want_to_change {}}} and it works fine. Did you try this?

For me /deep/ wouldn't pile.

I used ::v-deep:

.scoped-element {
    color:white;

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

Or

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

You could use ::ng-deep

Instead of:

.my-pagination /deep/ .ngx-pagination .current {
  background: #737373;
}

Try:

.my-pagination ::ng-deep.ngx-pagination .current {
  background: #737373;
}
