I am seeing the same error but have not figured out to make the correct version of libgit2 available. I tried having Brew install v1.2.0 (brew install [email protected]) but that did not work.

Any suggestions on how to make make this boat float would be appreciated.

As of libgit2/git2go#839 (comment) askgit needs to get git2go dependency bumped to v33

Thanks for bringing this up - I haven't been able to figure out how to pin the homebrew formula (and this might just be naivete on my part) to a specific dependency version.

So we have an issue where whenever the libgit2 formula gets a (breaking) version bump in homebrew, our homebrew installation will be broken until git2go and this repo are updated as well.

I'm sure there's a solution - if anyone knows of one off-hand, please let me know!

For now, I should have a "manual" fix up momentarily

This PR should address this issue: mergestat/homebrew-mergestat#12

@patrickdevivo First of all thanks for fixing this issue 👍 brew upgrade worked as expected for me with the updated askgit formulae.

So we have an issue where whenever the libgit2 formula gets a (breaking) version bump in homebrew, our homebrew installation will be broken until git2go and this repo are updated as well.

Yeah, it was my fault to give more-or-less false alarm. Apologies for that. When I took a more thorough look it became obvious that the issue is indeed with git2go and its dependency on libgit2 rather than with askgit. This is why I created issue in their repo to get it fixed and hence to bring an update to askgit.
