Expected behavior

The installation can pass without any issue

      error: command 'gcc' failed: No such file or directory

You have to install gcc

[rfan1]

Sorry, I forgot this one, with gcc installed, pip install pygit2 can still hit issue.

[dcermak]

you need to install the python headers too

Thanks much @dcermak, the issue is gone after installing python3-dev and libgit2-dev.

Best,
