Did you run bin/setup?

[kateinoigakukun]

Ah, sorry, I guess you did not do git submodule update

[krmbn0576]

i did run twice, so third trial now is below.

$ ./bin/setup

Could you try removing vendor/jco and git submodule update, then bin/setup again?

[krmbn0576]

$ rm -rf vendor
$ git submodule update

error[E0463]: can't find crate for `core`
  |
  = note: the `wasm32-wasi` target may not be installed
  = help: consider downloading the target with `rustup target add wasm32-wasi`

error[E0463]: can't find crate for `compiler_builtins`

For more information about this error, try `rustc --explain E0463`.
error: could not compile `cfg-if` (lib) due to 2 previous errors
warning: build failed, waiting for other jobs to finish...
Error: command exited with non-zero code `cargo build --workspace --target wasm32-wasi`: 101

so i did rustup target add wasm32-wasi , finally succeeded!
Hmm it seems to depend on the rustup target, so could you please add it to the CONTRIBUTING.md?
Thanks!

Actually, vendor/jco is a temporal solution to make it work before the Kaigi but I should note it in the guide

[kateinoigakukun]

I've upstreamed all necessary fixes in jco, so jco is no longer vendored as a submodule
