Problem encountered during installation of DeePMD-kit from Source Code

[ken-wooo]

Dear all,
I am installing DeePMD-kit from the source code and I follow the instruction from the document [https://github.com/deepmodeling/deepmd-kit/blob/master/doc/install/install-from-source.md#install-the-python-interface]. When I execute the command 'pip install ./' in the dir of deepmd-kit2.2.7, I encounter an error like this,

'''

It seems that ' the Field project.version has an invalid type, expecting a string (got None) '. I am wondering the reason of such an error and I hope to solve the problem for further installation.
Wish anyone could give me some advices? Many thanks!

With best regards,
Ken

Thanks for your guidance!! However, I have installed git with version 1.8.3.1. What could I do to solve the problem?
I am still a new comer about these. 😂
Thanks a lot !!

Did you use git clone?
