Delphi將組件安裝在自己的程序包中

Question

我已經開發了兩個單位文件（.pas），並且我有2個不同的組件，第一個是MyPCButton，第二個是MyPanel

MyPCButton.pas使用MyPanel.pas

問題是當我嘗試將它們放在單獨的軟件包中時，當我安裝使用MyPanel.pas的MyPCButton組件時，該軟件包會將它們都安裝在同一軟件包中，如果我先安裝MyPanel.pas，則MyPCButton軟件包將拒絕安裝並說“無法在包輸出目錄中為MyPanel.bpl創建輸出文件”

我將MyPanel放置在接口部分，並將其放置在實現部分，但仍然出現相同的錯誤，

我想做的是將它們單獨安裝在自己的軟件包中

Answer 1

關於您要做什么，沒有什么特別之處，但是您的實現以及描述將pas文件安裝到軟件包中的方式表明您可能不清楚如何進行。

首先，將組件和IDE注冊結合在同一個程序包中一直被認為是不好的做法。

您應該在“ 僅運行時”程序包中實現組件。 然后，您將獲得一個設計 時程序包，其中的需求列表中包括相應的運行時程序包。

設計時程序包還包含（通常）單個單元，該單元使用包含組件的單元並實現Register函數。

然后，將設計時程序包安裝到IDE中，IDE將根據需要加載運行時程序包以注冊組件。

在這種總體方法中，您仍然可以使用多種方法來組織軟件包。

您可以為每個控件使用單獨的運行時程序包，並為單獨安裝每個控件使用單獨的設計時程序包，但是聽起來您的程序包之間將具有很多依賴關系，而這些依賴關系很快會變得難以解開，並無法按您創建的順序創建依賴關系構建並安裝您的軟件包。

在你的情況，因為你的兩個組成部分互相之間有這種依賴關系，這聽起來像它將使最有意義的，以保持這些組件在一個單一的運行時包，並有一個單一的設計時包安裝從運行包中的所有組件。

如果確實需要，您仍然可以有單獨的設計時程序包來從該單個運行時程序包中分別安裝每個控件，但是我真的沒有發現這樣做的任何好處（除非存在進一步的復雜性或考慮因素）從您的問題中看不出來）。

這是我的錯

我已經更改了默認的dcp輸出目錄，顯然我不得不在庫路徑中添加新路徑，因此現在我可以將.pas文件放入/安裝在自己的包中
