我得到的錯誤沒有這樣的文件或目錄存在,它是混亂地獄我。我不想幫助填補我的方法或任何事情,我想爲自己做。我想修復這個錯誤,以便我可以開始使用我的項目。沒有這樣的文件或目錄存在
這是我的錯誤: My Error
這裏是我的代碼,其中的錯誤發生。如果您需要其他任何東西,我會很樂意更新我的問題,或提供相關信息。由於任何人誰幫助

我明白這是dlinkedlist.h的代碼。你還創建了一個名爲dlinkedlist.cpp的文件嗎? –
「dlinkedlist.cpp」確實存在,對吧?它和頭文件在同一個目錄下? – AndyG
@KenWhite是的。我也必須掃描所有標題才能找到包含在最後的:( –
