ValueError: zero length field name in format

[thatMrSheep]

OS:CentOS6.9
git version 2.9.3

I have installed the program with
wget -O - https://raw.githubusercontent.com/alberthier/git-webui/master/install/installer.sh | bash

then cd to my local gitclone, execute git webui
and it reported this

it seems that the webui can not read some config, so i check the .gitconfig

so how to solve this?

What is your python version ? You may be using an old one
