.net 无法在dotnet还原中解析runtime.ubuntu

我的Windows 7计算机上安装了dotnet 1.0.0-preview2-003131。当我在.NET核心项目的目录中使用cmd运行命令

dotnet restore

时，会出现以下错误：

myproject.json如下所示：

{
    "version": "1.0.0-*",
    "buildOptions": {
        "debugType": "portable",
        "emitEntryPoint": true
    },

    "dependencies": {
        "Microsoft.NETCore.App": {
            "version": "1.0.1"
        }
    },
    "frameworks": {
        "netcoreapp1.0": {
            "imports": "dnxcore50"

        }
    },
    "runtimes": {
        "win7-x64": {},
        "ubuntu.16.04-x64": {}
    }
}

删除

project.json

文件的

runtimes

部分，或者至少删除

ubuntu.16.04-x64

行

除非您正在构建一个应用程序，否则不需要

运行时

部分

如果你评论这一行

“ubuntu.16.04-x64”：{}
