Мой клиент настаивает на том, что команда fab doit('my_ssh_key') refresh('dev') работает в Windows (обновляет удаленный сервер разработки).

Итак, я попробовал команду в Linux (mint) и получил "bash: syntax error near unexpected token (‘»`.

Итак, я добавил кавычки, fab "doit('my_ssh_key')" "refresh('dev')" и я получил сообщение об ошибке в заголовке (такое же, как когда я экранировал скобки косой чертой).

Как мне заставить это работать?

Вот fabfile. fabfile.py:

# fab doit(path_to_ssh_key) maintenanceon('dev|staging')
# fab doit(path_to_ssh_key) maintenanceoff('dev|staging')
#
# fab doit(path_to_ssh_key) productionrefresh

# Example: fab doit('c:userstom.sshid_rsa.pem') maintenanceon('dev')

Я последовал за ответом RedKrieg и получил следующую ошибку:

Я получил эту ошибку, выполнив оба fab doit --keypath='cf_key' refresh --server='dev' и fab doit 'cf_key' refresh 'dev'

Ваша проблема не имеет ничего общего с fabric. Ваш клиент лжет вам, потому что этот синтаксис никогда (и не может быть) использован с инструментом командной строки fab. Чтобы передать аргументы в fab-задачу в fabric2 (которую вы используете в своем коде на python здесь), вы должны использовать аргументы задачи в стиле invoke. Для ваших примеров ниже приведены примеры правильного синтаксиса:

 #positional arguments
fab doit 'c:userstom.sshid_rsa.pem' refresh 'dev|staging'

#named arguments, equals is optional
fab doit --keypath='c:userstom.sshid_rsa.pem' maintenanceon --server='dev|staging'
