在OS X上编译失败的蛋糕，找不到msbuild.exe

Question

我想为我的Xamarin项目安装Cake build。它在Windows上完美工作，但在OS X（El Captain）上失败。 build.sh is here,build.cake is here。

，生成失败与NuGetRestore此消息：

MSBuild auto-detection: using msbuild version '4.0' from '/Library/Frameworks/Mono.framework/Versions/4.4.2/lib/mono/4.5'. 
MsBuild.exe does not exist at '/Library/Frameworks/Mono.framework/Versions/4.4.2/lib/mono/4.5/msbuild.exe'. 
An error occured when executing task 'Restore-NuGet-Packages'. 
Error: NuGet: Process returned an error (exit code 1). 

运行./build.sh -v “诊断” 给出：

这可能是因为在路径上NuGet.exe的版本那不知道单声道。

通过运行build.sh -v "Diagnostic"，您将得到如何为恢复操作调用NuGet命令行的详细日志。

还有用于NuGetRestore(FilePath, ​NuGetRestoreSettings)​过载的NuGetRestoreSettings可以将Verbosity属性设置为Detailed从的NuGet命令行获取更多详细的日志记录。

如果它不是项目工具文件夹中的nuget.exe，则可以更改引导程序以首先在路径中添加工具文件夹。 （你也可以在NuGetRestoreSettings上设置ToolsPath属性

如果它正在运行NuGet.exe的路径，通过运行nuget而不带参数（mono ./tools/nuget.exe）来检查你的nuget版本。

以供参考，这似乎是一个已知问题的NuGet控制台，参考GitHub的问题NuGet/Home#3085
