CakeBuild:安装工具“NUnit.ConsoleRunner”失败

Question

我使用CakeBuild来构建和测试我的Xamarin便携式类库。

在build.cake脚本中，我定义要使用NUnit-控制台来运行测试用例。所以我知道

#tool nuget:?package=NUnit.ConsoleRunner

不幸的是，当我运行Cake脚本时，我会得到以下错误。

Preparing to run build script...
VERBOSE: Restoring tools from NuGet...
VERBOSE: Feeds used:
  C:\Users\bergkar\.nuget\packages\

All packages listed in C:\dev\Xamarin\fleetboard-core-library\tools\packages.config are already installed.

Unable to find package 'NUnit.ConsoleRunner'
NuGet exited with 1
Could not find any relevant files for tool 'NUnit.ConsoleRunner'. Perhaps you need an include parameter?
Error: Failed to install tool 'NUnit.ConsoleRunner'.

当我添加一个特定的版本时，我想像下面这样使用，那么一切都很好。

#tool nuget:?package=NUnit.ConsoleRunner&version=3.7.0

有人能告诉我为什么没有版本的东西就不能工作吗？

通过使用".\build.ps1 -Verbosity诊断“，我得到了以下输出：

现在我发现了我的问题并解决了它。

问题是NuGet.exe没有指向像"https://api.nuget.org/v3/index.json“这样的公共nuget源的源提要。

这是因为我在"C:\Users\YOUR_USER_HOME\AppData\Roaming\NuGet“下的默认NuGet.conf没有定义packageSource。因此Nuget只知道"C:\Users\YOUR_USER_HOME.nuget\packages“下的本地nuget包缓存，而这并不包括指定的包。

因此，在"C:\Users\YOUR_USER_HOME\AppData\Roaming\NuGet\NuGet.Conf“中添加了一个packageSource之后，一切都很好。

另一种方法是在NuGet.Conf文件旁边添加一个新的build.ps1文件，其中包含CakeBuild和Xamarin项目所需的所有包源。

下一页解释Nuget如何找到它的配置。也许这有助于理解NuGet用于查找其配置的机制：https://learn.microsoft.com/en-us/nuget/consume-packages/configuring-nuget-behavior
