我正在尝试写入启用宏的 excel 文件 (xlsm)，然后运行一个取决于我的脚本正在写入的单元格的宏。为了清楚起见，我在 Windows 机器上，我不是管理员，我正在使用 python3.8.0

我有一个名为write.py的文件，在这个文件中，它将昨天的日期写入 A1 单元格，除非它是星期一，然后它写入星期五的日期。在它写入日期之后，我想运行一个使用该单元格/日期做某事的宏。

到目前为止，我可以写昨天的日期并且可以运行宏，但我不能在同一个文件中执行它们。我尝试从write.py文件中分离文件并执行宏，但这给了我同样的错误。

这是我的write.py文件的代码，该文件将昨天的日期写入 xlsm 文件的 A1 单元格：

from datetime import date
from datetime import timedelta
import openpyxl

path = "C:/Users/project/file.xlsm"

# loads the workbook into a var
book = openpyxl.load_workbook(path)
sheet = book["Sheet2"] # loads a specific sheet by name into a var
a1 = sheet['A1'] # loads a cell into a var

# testing
print(book.sheetnames)
print(a1.value)

# Get yesterdays date unless its a Monday then get Fridays date
today = date.today() 
if date.today().weekday() == 0: 
    yesterday = today - timedelta(days=today.weekday()) + timedelta(days=4, weeks=-1)
else:
    yesterday = today - timedelta(days = 1)

yestFormat = (yesterday.strftime("%x")) # formatting the date 

# setting the value of the A1 cell to the yesterFormat var
sheet.cell(row=1,column=1,value=yestFormat)
book.save(path)

# This file is supposed to run the macro
exec(open('runMacro.py').read())

这是应该运行宏的第二个文件的代码，我在write.py文件中也有这个代码，我遇到了同样的问题

import xlwings as xw

# loads the workbook into workbook var then loads a specific sheet into worksheet var
wb = xw.Book(r'C:/Users/project/file.xlsm')
wb.macro('test_macro')()
wb.save(r'C:/Users/project/file.xlsm')

当我运行带有注释掉的 exec 命令的write.py文件时，它可以工作并将日期写入单元格。所以我执行宏的方式有问题。我注意到如果 excel 文件已打开，那么write.py文件将不起作用，而runMacro.py文件在我运行时会打开 excel 文档。我认为这与它如何保存或打开有关，但我已经阅读了 xlwings 文档，并且我正在按照它所说的如何保存，所以我不确定。希望有更好的方法，谢谢反馈。

编辑：对不起，我忘了添加我得到的错误。出于隐私原因，我已更改文件路径，因此可能存在一些不一致之处。
