go install fails with too many errors

[veqryn]

Trying to use this project, but I can't even install it:
go install github.com/contiamo/openapi-generator-go/v2
Gives too many errors.

I am on Mac OS X with Golang 1.23

unfortunately, i can't reproduce this because I don't have a Mac. However, the cross-compile on Linux to Mac is working successfully for me.

Interestingly, it is also failing in CI during the release build

I will need to investigate some more.

I have reproduced your errors locally and they only happen when kin-openapi is incorrectly upgraded. Which is a very weird thing for go install to do on it's own, it should respect the pinned version in the mod file.
