"ResolveLibraryProjectImports"任务意外失败 [英] The "ResolveLibraryProjectImports" task failed unexpectedly

问题描述

我有一个基于MvvmCross的Xamarin项目.该项目适用于iOS和Android.我在Visual Studio 15中打开了这个项目.我遇到了一些错误，这些错误很快就解决了.有些错误会卡住，即使在Google和Stackoverflow上搜索后，我也无法解决.我已经尝试了Stackoverflow上发现的每个方法，但是仍然存在所有剩余的错误. 该项目使用的是诸如RestSharp和BoxApi.V2之类的第三方库(更多)

I have a Xamarin project, which is based on MvvmCross. The project is for both iOS and Android. I opened this project in Visual Studio 15. I got some errors, which I solved in no time. There are some errors, which are stuck and I couldn't solve them even after searching on Google and on Stackoverflow. I have tried each and every method found on Stackoverflow, but still all remaining errors are there. This project is using 3rd party libraries like RestSharp and BoxApi.V2 (few more)

我在下面发布我的错误日志.

I am posting my error log below.

Severity    Code    Description Project File    Line    Suppression State
Error       The "ResolveLibraryProjectImports" task failed unexpectedly.
System.IO.FileNotFoundException: Could not load assembly 'RestSharp(Android), Version=0.0.0.0, Culture=neutral, PublicKeyToken='. Perhaps it doesn't exist in the Mono for Android profile?

   at Microsoft.Build.BackEnd.TaskBuilder.<ExecuteInstantiatedTask>d__26.MoveNext() BoxApi.V2 (Android)

此错误对于此解决方案中包含的所有项目都重复.因此，我多次遇到此错误.

This error is repeating for all projects included in this solution. So I am getting this error multiple times.

我还想补充一点，该项目以前是基于MAC构建的，并且我使用的是Windows，这是否带来一些兼容性或跨OS问题? 我检查了所有程序集引用，并且一切正常.

I also want to add that the project was previously built on MAC and I am using windows, does this make some compatibility or cross OS issue? I have checked all assembly references and all are working fine.

推荐答案

我刚在Visual Studio 2017中使用全新的Xamarin.Forms应用程序进行了此操作.

I've literally just had this with a brand new Xamarin.Forms application in Visual Studio 2017.

根本原因似乎是我让VS2017在默认位置'C:\ Users \ Dave \ Documents \ Visual Studio 2017 \ Projects'中创建项目，这导致多个文件之一现在具有路径太久了.

The root cause appears to be that I let VS2017 create the project in it's default location 'C:\Users\Dave\Documents\Visual Studio 2017\Projects' and this has resulted in one of more files now having a path which it too long.

我将解决方案移到了D驱动器的根目录，它的构建没有任何问题.

I moved the solution to the root of my D drive and it builds without any problem.
