error could not find wasm-opt, set the WASMOPT environment variable to override during build

[vivekskrishna]

Tried runnign go run mage.go build with
tinygo version 0.31.2 and go version 1.21 5 and got following error
go: downloading github.com/petar-dambovaliev/aho-corasick v0.0.0-20230725210150-fb29fc3c913e

error: could not find wasm-opt, set the WASMOPT environment variable to override
Error: running "tinygo build -gc=custom -opt=2 -o build/mainraw.wasm -scheduler=none -target=wasi -tags='custommalloc nottinygc_envoy no_fs_access memoize_builders coraza.rule.multiphase_evaluation'" failed with exit code 1
exit status 1

Any diea how to resolve this. When googling i found this is because binaryen is not available. is it something that needs to be installed?

Feels like tinygo-org/tinygo#2319. Can you go to tiny go 0.30 or wait for #282 to be merged?

FYI #282 is merged. Master now builds with tinygo 0.31.2 and go 1.20. I confirm the issue JC pointed to, I faced the same problem and it is why I used tinygo binary downloaded from the repository and I had to install the binaryen dependency
