Я не являюсь разработчиком Ruby, и мне трудно установить Redmine (разработанный в Ruby) на сервер Ububuntu 16.04.
Я следую этому официальному учебнику: http://www.redmine.org/projects/redmine/wiki/HowTo_Install_Redmine_on_Ubuntu_step_by_step
Это кажется очень простым, но я нахожу много трудным, когда он «гарантирует, что GEM-пакет установлен».
Я не уверен, что именно этот GEM-пакет должен быть установлен. Из того, что я понимаю (поправьте меня, если я делаю неправильное утверждение), GEM - это то, что упаковывает исполняемое приложение Ruby (что-то вроде файла JAR в Java).
Итак, проблема в том, что, когда я выполняю это утверждение в консоли bash:
sudo gem updateЯ получаю много сообщений об ошибках, как это:

--------------------Итак, читая предыдущий файл журнала, кажется, что проблема может быть связана с:
fatal error: sqlite3.h: No such file or directoryКажется, что заголовочный файл C отсутствует, но я действительно не знаю, почему.
Почему у меня есть эта проблема? Что мне не хватает? Как я могу попытаться решить эту проблему?
