Build wasm failed, but build go binary is work

[Rory-Z]

What version of Go are you using (go version)?

$ go version
go version go1.21.3 darwin/amd64

Does this issue reproduce with the latest release?

Yes, the this issue reproduce in the 1.21.3

What operating system and processor architecture are you using (go env)?

What did you do?

I want build wasm like this blog: https://go.dev/blog/wasi, but I got this error:

$ GOOS=wasip1 GOARCH=wasm  go build -a -o manager.wasm main.go
# sigs.k8s.io/controller-runtime/pkg/certwatcher
../../../go/pkg/mod/sigs.k8s.io/controller-runtime@v0.12.3/pkg/certwatcher/certwatcher.go:97:34: cw.watcher.Events undefined (type *fsnotify.Watcher has no field or method Events)
../../../go/pkg/mod/sigs.k8s.io/controller-runtime@v0.12.3/pkg/certwatcher/certwatcher.go:105:32: cw.watcher.Errors undefined (type *fsnotify.Watcher has no field or method Errors)

but when I build go binary, looks good

$ go build -a -o manager main.go && echo $?
0

the code is from https://github.com/emqx/emqx-operator, I'm this repo owner, but I just want learning wasm, so can ignore this repo.

What did you expect to see?

I want build wasm successfully

What did you see instead?

looks like the library doesn't support the platform.
