Я не могу создавать таблицы (т.е. запускать db: migrate) в Rail 6 на Windows 7.
На всякий случай я полностью переустановил rails, установив пакет разработки Ruby 2.6 и выполнив 'gem install rails', который для меня установил Rails 6.0.3.1
Я создал новый проект и первым делом сгенерировал модель 'Customer', после чего я запустил команду db: migrate сразу после того, как она не сказала «было дано неправильное количество аргументов». См. Ниже.
