The examples do not have their own go.mod file. You can run them from the root of the project like:
PS C:\BirdMtnDev\Resources\ebitenui> go run ./_examples/widget_demos/button
PS C:\BirdMtnDev\Resources\ebitenui> go build ./_examples/widget_demos/button
PS C:\BirdMtnDev\Resources\ebitenui> ./button.exe
PS C:\BirdMtnDev\Resources\ebitenui>

Or if you use VS code there are run commands setup for each.
If you want to copy the code, you will need to build your go.mod file as needed.

This section of the error message you see is the key. You would need to run each of those "go get" commands.

makes go build work, but go mod tidy after the above go getting does not:

Is this normal?

That is not normal. I don't know why you would be seeing an issue like that

Turns out it was user error. Project cannot be in home dir. Moving anywhere else fixes it.

> go build
main.go:4:2: no required module provides package github.com/ebitenui/ebitenui; to add it:
        go get github.com/ebitenui/ebitenui
main.go:5:2: no required module provides package github.com/hajimehoshi/ebiten/v2; to add it:
        go get github.com/hajimehoshi/ebiten/v2

To test, use this one-liner: go clean -modcache; rm -f go.mod go.sum; go mod init domain.com/project; go mod tidy; go build

Workaround

> # Retrieves ebiten/v2 (v2.4.16) instead of ebiten/v2 (v2.4.18)
> go get github.com/ebitenui/ebitenui
> # OR get ebiten/v2 (v2.4.18) directly, and add ebitenui from go mod tidy
> go get github.com/hajimehoshi/ebiten/v2; go mod tidy

go mod tidy works after using one of the two above lines.

Cause (?)

ebitenui depends on ebiten/v2 (v2.4.16), but ebiten/v2 (v2.4.16) conflicts with ebiten/v2 (v2.4.18).

Proposed fix

Upgrade ebitenui/go.mod from ebiten/v2 v2.4.16 to ebiten/v2 v2.4.18.

So I just released a new version that is based on ebitengine's newest release 2.5.0. I believe that should resolve your issue. Let me know. I'm planning on closing this ticket in a few days unless there are any concerns that come up.

No comments in the past month and a new version was released again v0.5.0. I am closing this issue. Please reopen if you still have concerns.
