在python-3.3中使用pandas.ExcelWriter.to_excel时出错

我在python-3.3中使用pandas版本0.16.2和openpyxl版本2.2.4。 我正在编写一个非常简单的包含浮点数，string和NaN的pandas数据框。 当我使用代码时：

import pandas as pd writer = pd.ExcelWriter(xls_path) df.to_excel(writer,'sheet1') writer.save() 

我得到的错误：

 TypeError Traceback (most recent call last) <ipython-input-3-2349bf9de8ec> in save_xls(list_dfs, xls_path, sheetnames) 5 import pandas as pd 6 writer = pd.ExcelWriter(xls_path) ----> 7 df.to_excel(writer,sheetnames[n]) 8 9 writer.save() /Users/dylan/Virtualenvs/ve33/lib/python3.3/site-packages/pandas/core/frame.py in to_excel(self, excel_writer, sheet_name, na_rep, float_format, columns, header, index, index_label, startrow, startcol, engine, merge_cells, encoding, inf_rep) 1272 formatted_cells = formatter.get_formatted_cells() 1273 excel_writer.write_cells(formatted_cells, sheet_name, -> 1274 startrow=startrow, startcol=startcol) 1275 if need_save: 1276 excel_writer.save() /Users/dylan/Virtualenvs/ve33/lib/python3.3/site-packages/pandas/io/excel.py in write_cells(self, cells, sheet_name, startrow, startcol) 776 777 if style_kwargs: --> 778 xcell.style = xcell.style.copy(**style_kwargs) 779 780 if cell.mergestart is not None and cell.mergeend is not None: /Users/dylan/Virtualenvs/ve33/lib/python3.3/site-packages/openpyxl/compat/__init__.py in new_func(*args, **kwargs) 65 lineno=_code.co_firstlineno + 1 66 ) ---> 67 return obj(*args, **kwargs) 68 return new_func 69 TypeError: copy() got an unexpected keyword argument 'font' 

任何可能出错的帮助？

谢谢！

你能提供一种重现错误的方法吗？ 我使用Python 3.4，pandas0.16.2与Excel作家引擎openpyxl 。 以下示例代码在我的电脑上完美工作。

 import pandas as pd import numpy as np df = pd.DataFrame(np.random.randn(1000, 3)) xlsx_path = 'my_excel_file.xlsx' writer = pd.ExcelWriter(xlsx_path) df.to_excel(writer, 'Sheet1', engine='openpyxl')
