The repository you link to is owned by iysheng, who forked it from Laksen:

Both repositories look like they have not been maintained for the last 4 years.
For Laksen there is even a pull request (made by iysheng) to make a new branch for KiCad V5.

Support for Python V2 ended a year ago (2020-01-01) but due to some missing libraries KiCad still uses python V2 on windows and mac. On Linux, KiCad uses Python V3 but that also has some trouble in for example some of the Footprint Wizards which are now broken. (There is a patch, but it’s held back)

A general search:
… finds more forks. Among those:
And that fork apparently was patched for Python V3, so if you run linux that is worth a try.

Searching on github for repositories used to work before M$ took over, but now a search only finds one of the repositories, while I’ve just seen at least 3.

Hello Paulvdh,
Thank You for your quick replay . I will try this solution with Linux System. Thank you Once again.
