Failed to run hello world

[stusmall]

I just tried this project out this morning and hit an issue. I think I must have missed a step but not sure where. I can build simple projects but when running them I get an error that "wasi_snapshot_preview1" isn't found. The wasm file produced runs just fine in a bench build of wasmtime I have. I have a feeling I missed a step.

Following are versions and output from running

$ cargo wasi --version
cargo-wasi 0.1.20 (ad1e122eb2 2020-01-21)
$ rustc --version
rustc 1.41.0 (5e1a79984 2020-01-27)
$ cargo wasi run
    Finished dev [unoptimized + debuginfo] target(s) in 0.02s

error: failed to process main module `target/wasm32-wasi/debug/wasi-hello-world.wasm`
    caused by: Import module wasi_snapshot_preview1 was not found

Please let me know if you need any more information about my host set up

Thanks for the report! I think that you probably have an outdated version of wasmtime installed, but if you install the latest wasmtime from master you should be good to go!

That would do it. I definitely have an old one, I thought it brought its own. Thank you very much.,
