openpyxl + load_workbook + AttributeError:"NoneType"对象没有属性"date1904" [英] openpyxl+load_workbook+AttributeError: 'NoneType' object has no attribute 'date1904'

问题描述

当我使用openpyxl加载Excel文件(.xlsx)时，会显示此错误(最后一个链接是示例Excel文件):

When I use openpyxl to load the Excel file( .xlsx), this error displays (the last the link is the sample Excel file):

从openpyxl导入* wb = load_workbook("D:/develop/workspace/exman/test sample/510001653.xlsx")

from openpyxl import * wb = load_workbook("D:/develop/workspace/exman/test sample/510001653.xlsx")

回溯(最近通话最近一次):

Traceback (most recent call last):

文件"C:\ Python34 \ lib \ site-packages \ openpyxl-2.5.0-py3.4.egg \ openpyxl \ reader \ xcel.py"，第161行，在load_workbook中

File "C:\Python34\lib\site-packages\openpyxl-2.5.0-py3.4.egg\openpyxl\reader\ xcel.py", line 161, in load_workbook

parser.parse()

parser.parse()

文件"C:\ Python34 \ lib \ site-packages \ openpyxl-2.5.0-py3.4.egg \ openpyxl \ packagi g \ workbook.py"，第42行，处于解析状态

File "C:\Python34\lib\site-packages\openpyxl-2.5.0-py3.4.egg\openpyxl\packagi g\workbook.py", line 42, in parse

如果package.properties.date1904:

if package.properties.date1904:

AttributeError:'NoneType'对象没有属性'date1904'

推荐答案

我调试了python文件，并发现workbookPr = None，导致package.properties变为None(properties = Alias(workbookPr).如下的workbookParser.parser()代码，该错误已解决.

I debug the python file ,and find that the workbookPr = None , cause the package.properties to None( properties = Alias(workbookPr). So I change the code of workbookParser.parser() like follow, the error is solved.

class WorkbookParser:

def __init__(self, archive):
    self.archive = archive
    self.wb = Workbook()
    self.sheets = []
    self.rels = get_dependents(self.archive, ARC_WORKBOOK_RELS)


def parse(self):
    src = self.archive.read(ARC_WORKBOOK)
    node = fromstring(src)
    package = WorkbookPackage.from_tree(node)

    if package.properties is not None: #add this line 
        if package.properties.date1904:
            wb.excel_base_date = CALENDAR_MAC_1904
        self.wb.code_name = package.properties.codeName
   self.wb.active = package.active
