错误：'array-move‘不包含默认导出(作为’move‘导入)

Question

在文件夹中：./src/Components/Timeline/ReorderingModalNodes/use-position-reorder.js出现问题标题中提到的错误。但是array-move是一个包，所以我不确定如何修复它。如果问题不清楚，请让我知道，这样我就可以编辑更多信息

代码如下：

import { useState, useRef } from 'react';
import { clamp, distance } from 'popmotion';
import move from 'array-move';

export function usePositionReorder(initialState) {
  const [order, setOrder] = useState(initialState);

  // We need to collect an array of height and position data for all of this component's
  // `Item` children, so we can later us that in calculations to decide when a dragging
  // `Item` should swap places with its siblings.
  const positions = useRef([]).current;
  const updatePosition = (i, offset) => (positions[i] = offset);

  // Find the ideal index for a dragging item based on its position in the array, and its
  // current drag offset. If it's different to its current index, we swap this item with that
  // sibling.
  const updateOrder = (i, dragOffset) => {
    const targetIndex = findIndex(i, dragOffset, positions);
    if (targetIndex !== i) setOrder(move(order, i, targetIndex));
  };

  return [order, updatePosition, updateOrder];
}

const buffer = 30;

export const findIndex = (i, yOffset, positions) => {
  let target = i;
  const { top, height } = positions[i];
  const bottom = top + height;

  // If moving down
  if (yOffset > 0) {
    const nextItem = positions[i + 1];
    if (nextItem === undefined) return i;

    const swapOffset =
      distance(bottom, nextItem.top + nextItem.height / 2) + buffer;
    if (yOffset > swapOffset) target = i + 1;

    // If moving up
  } else if (yOffset < 0) {
    const prevItem = positions[i - 1];
    if (prevItem === undefined) return i;

    const prevBottom = prevItem.top + prevItem.height;
    const swapOffset = distance(top, prevBottom - prevItem.height / 2) + buffer;
    if (yOffset < -swapOffset) target = i - 1;
  }

  return clamp(0, positions.length, target);
};

正如错误所述，可能array-move不包含缺省导出，而只包含命名导入。

你能试试import { move } from 'array-move';吗？

还有，这就是https://www.npmjs.com/package/array-move吗？我在文档中看不到move方法。

因为在array-move中只有2个方法

arrayMoveMutable
arrayMoveImmutable

不能导入移动
