错误 NU1100：无法解决'HtmlAgilityPack (>= 1.11.45)'和'System.Drawing.Common (>= 6.0.0)' 'net6.0'

Question

这是我的csproj目标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HtmlAgilityPack和System.Drawing.Common。两者都兼容.Net 6.0(根据nuget(。在本地，我安装了用于net6.0:的.NET SDK

dotnet --info

然而，当我运行dotnet restore时，我得到了这个错误：

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

我在这里错过了什么？我认为dotnet restore应该没有错误地完成。

Answer 1

根据@PMF的建议。

1. 运行dotnet restore -v detailed，得到相同的错误
2. 从输出中找到全局nuget.config文件(C:UsersadminAppDataRoamingNuGetNuGet.Config(
3. 已检查配置：

<?xml version="1.0"?>
<configuration>
<packageSources>
</packageSources>
</configuration>

4. 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。
