使用openpyxl保存文件的時(shí)候，出現(xiàn)最下面異常，查看openpyxl 的版本是2.5.14， 把openpyxl降級(jí)就可以解決此問(wèn)題。
[root@billig mytest]# pip install openpyxl==2.5.11

補(bǔ)充：python的openpyxl 3.0.2版無(wú)法保存數(shù)據(jù)
在使用openpyxl3.0.2版的時(shí)候老是
報(bào)錯(cuò)“TypeError: got invalid input value of type , expected string or Element”
在將3.0.2版的卸載并且重新安裝了3.0.0版的openpyxl之后此報(bào)錯(cuò)解除！
以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教。
