Starting MailCatcher
~~> ERROR: Something's using port 1025. Are you already running MailCatcher?

Затем, когда я пытаюсь использовать http://localhost:1080/ показывает мне приложение mailcatcher. Но что мне нужно сделать с приложением, чтобы больше не показывать эту ошибку?

Answer 1

Кажется, что-то работает на этом порту. Это может быть другой экземпляр mailcatcher или какой-то другой процесс.

В большинстве систем *nix вы можете использовать следующую команду для поиска процесса, занимающего определенный порт:

lsof -i :PORT

Например:

lsof -i :1025

Результат будет содержать PID (идентификатор процесса). Вы можете использовать это, чтобы убить оскорбительный процесс.

kill -9 SOME_PID

Пример:

kill -9 32487
