Python openpyxl 無法保存文件的解決方案

Posted on by

使用openpyxl保存文件的時候，出現最下面異常，查看openpyxl 的版本是2.5.14， 把openpyxl降級就可以解決此問題。

[root@billig mytest]# pip install openpyxl==2.5.11
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

補充：python的openpyxl 3.0.2版無法保存數據

在使用openpyxl3.0.2版的時候老是

報錯“TypeError: got invalid input value of type , expected string or Element”

在將3.0.2版的卸載並且重新安裝瞭3.0.0版的openpyxl之後此報錯解除！

以上為個人經驗，希望能給大傢一個參考，也希望大傢多多支持WalkonNet。如有錯誤或未考慮完全的地方，望不吝賜教。
