.net-core - 简单哟项目上的 dotnet 恢复错误

Question

在 Fedorea 26 上运行，我正在构建我的第一个 dotnet core asp 应用程序。正在关注this教程，当我尝试下面的 dotnet restore 命令时，出现错误下面。

我怀疑问题是 yo 构建了一个 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？如果正确，我该如何升级 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

这是安装的 dotnet 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]$

哟还在ASP.NET Core 1.0 RC4 .还有一个要求ticket升级到 .NET Core 2.0。

最好的选择可能是使用 dotnet new。您可以键入 dotnet new -l 以列出所有可用模板。对于空的 Web 应用项目 dotnet new web。你可以查看this有关 dotnet new 的更多信息的链接。
