deep SassError: expected selector.

参考：https://blog.csdn.net/wwyxjjz/article/details/125845246

sass中deep报错

改用

::v-deep

如elementui中表格中input元素去掉内边距

::v-deep.table-full-input {
  .el-table__cell {
    padding: 0;
  }
  .cell {
    padding: 0;
  }
  .el-input__inner {
    padding: 4px;
  }
}

 vue3打包的时候会提示::v-deep usage as a combinator has been deprecated. Use :deep(<inner-selector>) in

改成

:deep(.el-form-item__label) {
  color: #fff !important;
}
