c# - 为什么 nuget 安装一堆系统命名空间引用？

Question

我正在尝试从 nuget 安装一个库。我期待可能有 3 或 4 个不同的依赖项，但它安装了 System 的整个负载依赖？

这是日志:

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

这最终使我的 packages超过 100mb 的文件夹充满了不需要的库。

以前从未经历过这种情况。

有任何想法吗？

Answer 1

Why is nuget installing a bunch of system namespace references?

恐怕是包TwitchLib.Client依赖的问题, WebSocket4Net和 SuperSocket.ClientEngine.Core .

检查错误日志后，您可以找到以下信息:

Attempting to gather dependency information for package 'TwitchLib.Client.2.1.4' with respect to project 'Twitch Logs', targeting '.NETFramework,Version=v4.6'

表示目标框架是 .NET 4.6 而不是 .NET Standard .

为了重现这个问题，我创建了一个项目目标 .net 4.6 ，然后安装nuget包WebSocket4Net , 然而 ，确认窗口显示它列出了安装部分下的依赖项，这似乎是从 WebSocket4Net 拉出来的。 .NETStandard 1.3依赖列表:



我之前已经报告过类似的问题 NuGet install the wrong dependencies ，您可以尝试安装Microsoft.Data.Services.Client 5.8.2到带有 .net 4.5.2 的 C# 项目。此问题已在 5.8.3 版中修复。

所以，为了解决这个问题，我们需要联系这个包的作者来更新这个包。包 SuperSocket.ClientEngine.Core 的相同问题.

注意:如果您不想将这些系统依赖项添加到您的项目中，您可以将它们从您的项目中删除。

希望这可以帮助。
