Question

我开发了两个单元文件（.pas），我有两个不同的组件第一个是MyPCButton，第二个是MyPanel

MyPCButton.pas使用MyPanel.pas

问题是，当我尝试将它们放在单独的软件包中时，当我安装使用MyPanel.pas的MyPCButton组件时，如果我首先安装MyPanel.pas，那么软件包会将它们安装在同一个软件包中，然后MyPCButton包拒绝安装并说“无法在包输出目录中为MyPanel.bpl创建输出文件”

我已将MyPanel放在接口部分，我已将其放在实现部分，但我仍然得到相同的错误，

我想做的是将它们分别安装在自己的包中

MyPCButton.pas：

<ul ng-repeat="(id,item) in items">
   Item {{id}}
   <li ng-repeat="(key,value) in item">
    {{key + '=>' + value}}
   </li>
</ul>

MyPanel.pas

Answer 1

您尝试执行的操作没有什么特别之处，但您的实现以及将pas文件安装到软件包中的方式表明您可能不清楚如何处理它。

首先，在同一个软件包中组合组件和IDE注册一直被认为是不好的做法。

您应该在仅限运行时的程序包（或程序包）中实现组件。然后，您有一个设计时包，其中包含相应的运行时包需要列表。

设计时包还包含（通常）单个单元，使用包含组件的单元并实现注册功能。

然后将设计时软件包安装到IDE中，IDE将根据需要加载运行时软件包以注册组件。

在整体方法中，您仍然可以选择多种方式来组织软件包。

你可以为每个控件分别设置运行时包，单独的设计时包分别安装每个控件，但听起来你的包之间会有很多依赖关系，这很快就会解决问题，并在命令中创建依赖关系在其中构建和安装包。

在您的情况下，由于您的两个组件之间存在相互依赖关系，因此将这些组件保留在一个运行时包中并使用单个设计时包来安装所有组件是最有意义的。来自该运行时包的组件。

如果真的希望您仍然可以使用单独的设计时软件包来单独从该单个运行时软件包安装每个控件，但我真的没有看到这样做的任何优势您的情况（除非您的问题中没有明显的进一步复杂性或考虑因素）。

Answer 2

这是我的错误

我更改了默认的dcp输出目录，显然我必须在库路径中添加新路径，所以现在我可以将.pas文件放入/安装在自己的包中

Delphi在自己的包中安装组件
