Daniel Macovei (Mar 16 2022 at 13:23): Daniel Macovei (Mar 16 2022 at 13:23):Hi I'm following these docs and getting an error even though I'm wadding the web assembly build target https://docs.wasmtime.dev/tutorial-create-hello-world.html

= note: the wasm32-wasi target may not be installed
= help: consider downloading the target with rustup target add wasm32-wasi
error: cannot find macro println in this scope

error: requires sized lang_item
fitzgen (he/him) (Mar 17 2022 at 15:56):it looks like you need to add the wasm32-wasi target, running the suggested rustup command should do the trick:
rustup target add wasm32-wasi
