“ Apple事件超时”，使用xlwings打开大型电子表格

Question

我正在MacOS上使用以下xlwings代码读取包含许多要执行的公式的大型Excel电子表格：

import xlwings as xl
app = xl.App(visible=False)
book = app.books.open("large.xlsx")
book.save()
app.kill()

尝试执行此代码会导致CommandError：“ Apple事件超时”，完整堆栈跟踪：

File "./open_excel_file.py", line 32, in open_excel_file
    book = app.books.open("large.xlsx")
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/xlwings/main.py", line 2889, in open
    impl = self.impl.open(fullname, update_links, read_only, format, password, write_res_password,
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/xlwings/_xlmac.py", line 209, in open
    self.app.xl.open_workbook(workbook_file_name=fullname, update_links=update_links, read_only=read_only,
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/aeosa/appscript/reference.py", line 518, in __call__
    raise CommandError(self, (args, kargs), e, self.AS_appdata) from e
appscript.reference.CommandError: Command failed:
        OSERROR: -1712
        MESSAGE: Apple event timed out.
        COMMAND: app('/Applications/Microsoft Excel.app', newinstance=(0, 34521322)).open_workbook(workbook_file_name='large.xlsx', update_links=k.do_not_update_links, read_only=None, format=None, password=None, write_reserved_password=None, ignore_read_only_recommended=None, origin=None, delimiter=None, editable=None, notify=None, converter=None, add_to_mru=None)

有没有一种方法可以使用xlwings打开此文件，执行所有公式，然后再次保存它，而不会遇到此超时？

Answer 1

xlwings当前与基础应用程序脚本的默认超时一起使用。如果在保存事件期间发生这种情况，您应该可以将其作为解决方法，直到此问题得到解决：workbook.api.save(timeout=3000)，请参阅：https://github.com/xlwings/xlwings/issues/618

编辑：

打开工作簿的过程是这样的：

import xlwings as xw
app = xw.App(visible=False)
book = app.api.open_workbook(workbook_file_name='large.xlsx', timeout=3000)

我将尝试在下一个版本中添加本机支持。
