错误 NU1100:无法为“net6.0”解析“HtmlAgilityPack (>= 1.11.45)”和“System.Drawing.Common (>= 6.0.0)”

[英]error NU1100: Unable to resolve 'HtmlAgilityPack (>= 1.11.45)' and 'System.Drawing.Common (>= 6.0.0)' for 'net6.0'

这是我的csproj针对net6.0

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="HtmlAgilityPack" Version="1.11.45" />
    <PackageReference Include="System.Drawing.Common" Version="6.0.0" />
  </ItemGroup>
</Project>

它需要两个库HtmlAgilityPackSystem.Drawing.Common 两者都兼容.Net6.0(根据nuget)。 在本地,我为 net6.0 安装了 .NET SDK:

dotnet --info
.NET SDK (reflecting any global.json):
 Version:   6.0.400
 Commit:    7771abd614

Runtime Environment:

global.json file:

  Commit:       55fb7ef977

.NET SDKs installed:
  6.0.400 [C:\Program Files\dotnet\sdk]

.NET runtimes installed:
  Microsoft.AspNetCore.App 6.0.8 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 6.0.8 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
  Microsoft.WindowsDesktop.App 6.0.8 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]

然而,当我运行dotnet restore时,我收到此错误:

  Determining projects to restore...
C:\Repos\test\test.csproj : error NU1100: Unable to resolve 'HtmlAgilityPack (>= 1.11.45)' for 'net6.0'.
C:\Repos\test\test.csproj : error NU1100: Unable to resolve 'System.Drawing.Common (>= 6.0.0)' for 'net6.0'.
  Failed to restore C:\Repos\test\test.csproj (in 104 ms).

我在这里想念什么? 我认为dotnet restore应该没有错误地完成。

根据@PMF 的建议。

  1. dotnet restore -v detailed ,得到同样的错误。
  2. 从 output 找到全局nuget.config文件( C:\Users\admin\AppData\Roaming\NuGet\NuGet.Config
  3. 检查了配置:
<?xml version="1.0"?>
<configuration>
  <packageSources>
  </packageSources>
</configuration>
  1. 添加了 nuget
<?xml version="1.0"?>
<configuration>
  <packageSources>
    <add key="NuGet" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
</configuration>

之后dotnet restore按预期工作。
