`air -v` not showing version when installed with `go install`

[roeniss]

Hi! The air and go versions are not shown on air -v on my computer.

• git clone https://github.com/cosmtrek/air && cd air && make install && air -v → shows versions well
• go install github.com/cosmtrek/air@latest && air -v → don't show versions well

> go install github.com/cosmtrek/air@v1.43.0
go: downloading github.com/cosmtrek/air v1.43.0
> air -v

> go install github.com/cosmtrek/air@latest
> air -v

I'm wondering this is known issue.

I think there is a bug. The airVersion used to bind ldflags is not exported, so I created a pull request #433.

The reason is that go install does not call make. It does not matter if the variable is exported or not.

It should use debug.BuildInfo, like this: makiuchi-d/arelo/arelo.go#L137-L141
