Mac系统,在jupyter中使用xlwings建立exce表后,用了wb.close()之后使用wb.save()会报错,反之亦然,两者只能输入一个

问题遇到的现象和发生背景
问题相关代码,请勿粘贴截图
import xlwings as xw
import time
app=xw.App(visible=False)
wb=app.books.open('data.xlsx')
wb=app.books.add()
ws=wb.sheets.add('t')
ws=wb.sheets[0]
ws.range('a1').value='hzx'

wb.close()
time.sleep(3)
wb.save(r'/Users/houzhixian/Desktop/phzx21.xlsx')
# app.quit()

运行结果及报错内容

The above exception was the direct cause of the following exception:

我的解答思路和尝试过的方法
我想要达到的结果

顺序反了,wb对象已经被你用wb.close()关闭了,所以不存在了,再用wb.save()就会报错。
先save再close
