Question

所以我安装了Visual Studio for Mac并运行了Sierra 10.12.1。在安装某些Nugets时遇到问题，同时解决Microsoft.AspNet.Core.Mvc问题（由于项目文件中的TargetFramework不是因为1.1.0），我正在与Microsoft.Extensions.Configuration.Json进行斗争。

以下是错误消息

如果微软有人认为这是其他一些问题：）

在Nuget套餐之后搜索的整体体验非常糟糕。一个人希望能够使用通配符进行搜索，或者至少期望它只是在输入Json时找到相关的包（找不到Microsoft.Extensions.Configuration.Json ......）。
同时报告VS的问题并不起作用，因为我在同一台计算机上发布此问题，因此我抱怨互联网连接。

Answer 1

首先安装依赖项self.然后添加Microsoft.Extensions.Configuration.FileExtensions导致安装成功！

编辑：不幸的是，快乐的时光早在我希望的时候。尝试安装EntityFrameworkCore时出现完全相同的问题，并且瞬态依赖项列表无法跟随bortom

Answer 2

我有类似的问题，我只是去管理NuGet包并将包更新到最新版本。这对我有用。
