Выяснил что если удалить пакет blocktrail/blocktrail-sdk, все нормально устанавливается и потом при попытке поставить blocktrail/blocktrail-sdk, опять получаю ошибки
Из всего этого я понял то что оба пакету нуждаются в одной зависимости, только одному из них нужна версия меньше чем другому...
Кто знает как решить это проблему?
