Bud: command not found

Hello there, i’m working on a theme using sage 10.2.0.
I followed all instructions in the docs and everything went fine during the installation with composer.
Now i’m stuck with this error:

% yarn dev
yarn run v1.22.19
$ bud dev
/bin/sh: bud: command not found
error Command failed with exit code 127.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

Same error trying to make a build.
I get into the same error with sage 10.2.0 and 10.1.7.

I’m using Local by flywheel, node 16.17.0 and yarn 1.22.19

thanks for any advice
