Can second this issue, had this when running on GitLab CI with image: python:3 in .gitlab-ci.yml.

I have no problem building this package under 3.9. You need to have libgit2 installed though.

$ docker run --rm -it python:3.9 bash

Sorry, I think I might slightly have misunderstood the problem. But the missing git2.h file is because you don't have libgit2 installed.
I think the info here might help
https://www.pygit2.org/install.html#advanced

Had a similar issue on macOS Catalina (10.15.7).

In my case I solved it by running brew install libgit2 before executing pip3 install pygit2 (thanks @buhl).

(I use Homebrew on this Mac)

[alecandido]

It is failing also on GitHub Actions: the same workflow run for 3.8, but it is failing on 3.9 because of the missing headers.

I would guess that setup-python action (the only difference in the workflow) should be independent on libgit2, so I believe that the two wheels are somewhat different. Will this problem be fixed?

Thanks @buhl that's correct, and the error message is very clear:

 [14:10:12] src/blob.h:33:10: fatal error: git2.h: No such file or directory
