Question

在Fedorea 26上运行，我正在构建我的第一个dotnet core asp应用程序。在this教程之后，当我尝试dotnet restore下面的命令时，我收到错误消息下方。

我怀疑问题是yo构建了dotnet core 1.x应用程序，但如下所示，我有dotnet core 2.0.0。

这是否正确，如果是，如何升级yo以构建dotnet 2.0项目？

yo aspnet

? What type of application do you want to create? Empty Web Application
? What's the name of your ASP.NET application? WeatherMicroservice
   create WeatherMicroservice/.gitignore
   create WeatherMicroservice/Program.cs
   create WeatherMicroservice/Startup.cs
   create WeatherMicroservice/WeatherMicroservice.csproj
   create WeatherMicroservice/web.config
   create WeatherMicroservice/Properties/launchSettings.json
   create WeatherMicroservice/runtimeconfig.template.json
   create WeatherMicroservice/README.md
   create WeatherMicroservice/global.json


Your project is now created, you can use the following commands to get going
    cd "WeatherMicroservice"
    dotnet restore
    dotnet build (optional, build will also happen when it's run)
    dotnet run


[idf@localhost asp-core]$ cd WeatherMicroservice/
[idf@localhost WeatherMicroservice]$ dotnet restore

The specified SDK version [1.0.0-rc4-004771] from global.json [/home/idf/Documents/asp-core/WeatherMicroservice/global.json] not found; install specified SDK version
Did you mean to run dotnet SDK commands? Please install dotnet SDK from: 
  http://go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409

这是dotnet已安装的版本：

[idf@localhost WeatherMicroservice]$ dotnet --info output:
The specified SDK version [1.0.0-rc4-004771] from global.json [/home/idf/Documents/asp-core/WeatherMicroservice/global.json] not found; install specified SDK version

Microsoft .NET Core Shared Framework Host

  Version  : 2.0.0
  Build    : e8b8861ac7faf042c87a5c2f9f2d04c98b69f28d

[idf@localhost WeatherMicroservice]$
