nuget为什么要安装一堆系统名称空间引用？

Question

我正在尝试从nuget安装一个库。我原本期望3或4个不同的依赖项，但是它安装了System个依赖项的整个负载？

这是日志：

========== Finished ==========

这最终使我的packages文件夹充满了100mb以上的不需要的库。

以前从未经历过。

有什么想法吗？

Answer 1

  

为什么nuget安装一堆系统名称空间引用？

恐怕这可能与软件包TwitchLib.Client，WebSocket4Net和SuperSocket.ClientEngine.Core的依赖性有关。

检查错误日志后，您可以找到以下信息：

  

尝试收集程序包的依赖项信息   关于项目“ Twitch Logs”的“ TwitchLib.Client.2.1.4”，   定位到' .NETFramework，Version = v4.6 '

这意味着目标框架是 .NET 4.6 而不是.NET Standard。

要重现此问题，我创建了一个项目目标.net 4.6，然后安装了nuget软件包WebSocket4Net，但是，确认窗口显示出来，它在安装部分下列出了依赖项，似乎是从WebSocket4Net .NETStandard 1.3依赖项列表中提取的：

在NuGet install the wrong dependencies之前我已经报告了类似的问题，您可以尝试使用.net 4.5.2将Microsoft.Data.Services.Client 5.8.2安装到C＃项目中。此问题已在5.8.3版中修复。

因此，要解决此问题，我们需要联系此软件包的作者以更新此软件包。软件包SuperSocket.ClientEngine.Core的问题相同。

注意：如果您不想将这些系统依赖项添加到您的项目中，则可以将其从项目中删除。

希望这会有所帮助。
