将环境变量获取到 WIX 属性中 [英] Get an environment variable into a WIX property

问题描述

有没有办法将 WIX 中的环境变量放入属性中?

Is there a way to get an environment variable in WIX into a property?

我正在尝试通过以下方式获取 USERPROFILE:

I'm trying to get the USERPROFILE with:

Property Id="UserFolder"  Value="$(env.USERPROFILE)EdwardsAppMyFolder"

但这只会获取构建机器的 USERPROFILE，安装程序就是在其中构建的.

But this only picks up the USERPROFILE of the build machine, where the installer is built.

我希望它使用正在安装应用程序的机器的 USERPROFILE.

I want it to use the USERPROFILE of the machine where the app is being installed.

推荐答案

您可以在安装过程中使用环境变量，但这需要使用自定义操作.您需要使用 UserFolder 属性rel="noreferrer">Type 51 Custom Action 而不是在构建期间设置属性.[%ENVVARNAME] 格式用于使用环境变量，但环境变量的名称区分大小写.

You can make use of Environment variables during installation but this requires using a custom action. You will need to set the UserFolder property with a Type 51 Custom Action as opposed to setting the property during the build. The [%ENVVARNAME] format is used to make use of an environment variable, but the name of the environment variable is case-sensitive.

设置属性的自定义操作的 WiX 示例:

<CustomAction Id="SetUserFolder" Property="UserFolder" Value="[%USERPROFILE]EdwardsAppMyFolder" />
