В Anjuta У меня есть следующие параметры для JavaScript среда .:
Я использую AntergOS (Arch Linux). Возможно, неверны Gir и . Неверные ссылки на Gjs, так как у меня есть сообщение о: const: Command not found?
В чем может быть проблема при вышеуказанной ошибке?
Я нашел родственную задачу для проекта Anjuta Java: How to import an existing Java project in the Anjuta IDE?
