::v-deep替换为了:deep

:deep .el-tree {
  background-color: #235ea73d;
  color: rgb(255, 255, 255) !important;
}

:deep .el-tree-node__content {
  &:hover {
    background-color: #235ea73d;
  }
}

// 选中背景色修改
:deep .el-tree-node.is-current>.el-tree-node__content {
  background-color: #235ea73d !important;
}
