Я начинающий рубин и пытаюсь понять и изучить рубин.Я столкнулся с этой ошибкой при попытке запустить файл ruby, который использует «требуют проклятия», но я получаю следующую ошибку при этом.Приветствуется любая помощь или подсказка.

Также, когда я проверяю версию ruby, она указывает на 2.3.3, но во время работы показывает мне, что ruby 2.3.0 запускает файл.Если бы кто-то мог объяснить, почему это также помогло бы мне.После установки гемов в файл вручную я получаю еще одну ошибку, см. Ниже.

Unable to load this gem. The libzmq library (or DLL) could not be found.
If this is a Windows platform, make sure libzmq.dll is on the PATH.
If the DLL was built with mingw, make sure the other two dependent DLLs,
libgcc_s_sjlj-1.dll and libstdc++6.dll, are also on the PATH.
For non-Windows platforms, make sure libzmq is located in this search path:
