I'm having trouble compiling wasmtime-wasi.

I'm on stable-aarch64-apple-darwin, Rust 1.70

My other dependencies are

[dependencies]
wasmtime = { version = "=10.0.1", features = ["component-model"] }
wasmtime-wasi = "=10.0.1"
anyhow = "1"
transformer = { path = "../transformer" }
tokio = { version = "1.11.0", features = ["rt-multi-thread", "macros"] }

error: could not compile `wasmtime-wasi` (lib) due to 4 previous errors

Some help would be appreciated thanks a lot :pray:

The error seems simple but since it is a published package I suppose this is happening because of a version clash of some sort.

A workaround for this is pinning.

[dependencies]
wasmtime-wasi = "=10.0.1"
cap-fs-ext = "=1.0.15"
cap-primitives = "=1.0.15"
cap-std = "=1.0.15"

cap-x 1.0.16 and up is the issue.

When we run cargo clean or update the transative dependency goes above 1.0.15.

I still leave it open since the maintainers would update to 1.0.16 and above in cap dependencies.

This issue is resolved. :tada:
