el-upload组件中清空已上传的文件

Question

el-upload组件中清空已上传的文件列表，使用这个方法的时候，无效，没有被清空，报错了TypeError: this.$refs.upflieload.clearFiles is not a function。可是我搜了好多帖子都是这么用的，这个是什么原因呀，怎么才可以使用呀

  <el-upload
              ref="upflieload"
              action="#"
              accept=".jpg,.png,.jpeg,.docx,.xlsx"
              multiple
              :limit="3"
              :http-request="httpRequest"
              :on-preview="handlePreview"
              :on-remove="handleRemove"
              :before-remove="beforeRemove"
            >
              <el-button size="small" type="primary">点击上传</el-button>
            </el-upload>
          </div>
          <el-button size="small" @click="clearFiles" type="primary"
            >清空</el-button
          >



 clearFiles() {
      this.$refs.upflieload.clearFiles();
    },
