Excel openpyxl.workbook.workbook.save（）方法出错

如果我有这个代码：

from openpyxl import Workbook

    wb = Workbook()
    ws = wb.create_sheet(0)
    ws.title = 'Title'

    ws.cell('A3').value = 8

    wb.save('temp.xlsx')

我得到一个错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.3/dist-packages/openpyxl/workbook.py", line 233, in save
    save_workbook(self, filename)
  File "/usr/local/lib/python3.3/dist-packages/openpyxl/writer/excel.py", line 159, in save_workbook
    writer.save(filename)
  File "/usr/local/lib/python3.3/dist-packages/openpyxl/writer/excel.py", line 142, in save
    self.write_data(archive)
  File "/usr/local/lib/python3.3/dist-packages/openpyxl/writer/excel.py", line 83, in write_data
    self._write_worksheets(archive, shared_string_table, self.style_writer)
  File "/usr/local/lib/python3.3/dist-packages/openpyxl/writer/excel.py", line 104, in _write_worksheets
    style_writer.get_style_by_hash()))

    for range_string, rules in worksheet.conditional_formatting.cf_rules.iteritems():
AttributeError: 'dict' object has no attribute 'iteritems'

我甚至连最简单的电子表格都做不到。它们都显示了这个错误

openpyxl 1.8.0/python 3.3.2

我做错了什么

更新：python脚本是针对Python3的，但是如果我使用Python2.7.5运行它，脚本就可以工作

有人能告诉我为什么吗？

这绝对不是2014年1月才发布的openpyxl 1.8。最初的bug在1.7中得到了修复，它通过了Python3中Python2.5、2.6、2.7、3.2和3.3的所有测试，dicts只有一个.items方法。它在Python2.7中工作，因为在该版本中dicts同时具有.iteritems和.items方法。在最新消息来源中，问题似乎已得到解决：
