念のためrustup updateしました。
変わりませんでした。
Rubyのバージョンの問題かもしれません。
rbenv local 3.4.0-preview1 gem install ruby_wasm

変わっていなさそうです。 Ruby 3.3.1だと？

しゅっと行きました。
ruby.wasm開発用にビルドしていたgemが使えたみたいです。
せっかくなのでrbwasmコマンドをつかってみましょう。

おお、これはruby.wasm自体をビルドするときによく見る奴です。 RubyのVMをコンパイルしています。 考えてみれば当たり前ですが、ruby.wasmをビルドするときと同じ手順を踏むんですね。
せっかくなのでruby.wasmファイルにgemを書き込んでみます。 とりあえず slim をインストールします。 C拡張を使っていなければ何でも良いです。
ledsun@MSI:~/ruby.wasm-test►bundle add slim Fetching gem metadata from https://rubygems.org/.. Resolving dependencies... Fetching gem metadata from https://rubygems.org/.. Resolving dependencies... Fetching temple 0.10.3 Installing temple 0.10.3 Fetching slim 5.2.1 Installing slim 5.2.1
bundle exec rbwasm build -o ruby.wasm してみます。

おお、すごい。 ruby.wasmファイルにgemが書き込まれています！ はー、つまりGemfile.lockをみて必要なgemを探してきて書き込んでいるのでしょうか？
ついでにC拡張を使ったgemも試してみましょう。
bundle add rexml bundle exec rbwasm build -o ruby.wasm
こちらは失敗します。
