WebAs tracked in this ticket, Boost.Python does not fully support std::shared_ptr. In short, two easy solutions are to either: Use boost::shared_ptr instead of std::shared_ptr. Expose the std::shared_ptr member variable with via add_property (), providing a boost::python::return_value_policy with a type of boost::python::return_by_value. Web那么，為什么我會收到有關 Python 沒有為 boost::shared_ptr 注冊 class 的投訴？感謝你給與我的幫助。（上面的代碼已被修剪，因此在編寫問題的過程中可能引入了拼寫錯誤）。接受 Valeca 的建議，我重新完成了傳回 vector 的工作（消除了 boost::shared_ptr）。 flyer zeg
