Development

$ rake static/irb.wasm   # You can omit the argument as default task makes static/irb.wasm
$ npm install
$ rake parcel

Clean build

If you need to re-build Ruby itself (when you made a change to Ruby), clean rubies and build directories by rake deep_clean, then re-execute rake static/irb.wasm

If you just made a change to fake-gems, you only need to remove static/irb.wasm by rake clean and re-execute rake static/irb.wasm to avoid rebuilding everything.
