cabal 3.x у меня не работает.
Я хотел использовать песочницу, как в cabal 2.x. Но установка пакетов кажется успешной или нет.
В документации сказано, что команды v1- все еще доступны.
Но как такое возможно:
cabal v1-build говорит cabal: Encountered missing or private
dependencies
и
cabal v1-install --only-dependencies говорит All the requested packages are already installed
Журнал оболочки:

Use --reinstall if you want to reinstall anyway.
