I created a simple NuGet package that includes an Init.ps1 script in the Tools folder. The script starts as follows:
我创建了一个简单的NuGet包，其中包含Tools文件夹中的Init.ps1脚本。该脚本如下所示：
param($installPath, $toolsPath, $package, $project)
$postBuildEvent = $project.Properties.Item("PostBuildEvent").Value
When installing the package in a Visual Studio 2012 project I get an error on $project.Properties.Item, because $project.Properties is null: "You cannot call a method on a null-valued expression". I checked if $project.Properties is null and it is.
在Visual Studio 2012项目中安装软件包时，我在$ project.Properties.Item上收到错误，因为$ project.Properties为null：“您无法在空值表达式上调用方法”。我检查了$ project.Properties是否为null。
Question is, why it is null. I just try to alter the post build event (like described here). Does anyone have clues?
问题是，为什么它是null。我只是尝试改变post build事件（如此处所述）。有人有线索吗？
Edit: If the code is inside Install.ps1 it works. It seems that the project properties are not available when first installing a package.
编辑：如果代码在Install.ps1中，它可以工作。首次安装软件包时，似乎项目属性不可用。

The parameter list for init.ps1 is:
init.ps1的参数列表是：
param($installPath, $toolsPath, $package)
init.ps1 does not have the $project parameter because it is executed at the solution level and is not dependent on project.
init.ps1没有$ project参数，因为它在解决方案级别执行，并且不依赖于项目。
