我具有以下设置,但仍然无法将mvmcross库添加到我的项目中:
I have the following setup and still couldn't add mvmcross libraries to my project:

You are trying to install this package into a project that targets 'portable-net45+win+wp80+Xamarin.iOS10+MonoAndroid10+MonoTouch10', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.推荐答案
问题是,NuGet 2.8.2未将Xamarin.iOS框架(它是iOS Unified项目的新框架)视为可选框架(将可移植类库(PCL)程序集安装到PCL项目中时,请使用2.8.50313.46)或更高版本. NuGet 2.8.2将MonoAndroid和MonoTouch视为可选,但不将其作为Xamarin.iOS.
The problem is that the Xamarin.iOS framework, which is a new framework for iOS Unified projects, is not treated as an optional framework by NuGet 2.8.2 (2.8.50313.46) or older when installing a Portable Class Library (PCL) assembly into a PCL project. NuGet 2.8.2 treats MonoAndroid and MonoTouch as optional but not Xamarin.iOS.
因此,您可以选择以下选项之一:
So your options are one of the following:
NuGet 2.8.3 alpha已被修改,因此它知道Xamarin.iOS框架并将其视为可选.
NuGet 2.8.3 alpha has been modified so it is aware of the Xamarin.iOS framework and treats it as optional.
新的Xamarin.iOS PCL配置文件xml文件由较旧的Xamarin 3.6版本之一安装.最新的Xamarin 3.6版本不会安装新的iOS统一PCL配置文件xml文件,并且需要第二个安装程序会安装NuGet 2.8.3 alpha和新的配置文件xml文件.
The new Xamarin.iOS PCL profile xml files were installed by one of the older Xamarin 3.6 releases. The latest Xamarin 3.6 release does not install the new iOS unified PCL profile xml files and requires a second installer which installs NuGet 2.8.3 alpha and the new profile xml files.
如果您选择选项2),请注意,这样做会阻止将NuGet软件包(例如MvvmCross.PortableSupport)安装到Xamarin.iOS Unified项目中.
If you go for option 2) please be aware that doing so will prevent the installation of NuGet packages, such as MvvmCross.PortableSupport into a Xamarin.iOS Unified project.
