安装nuget包"已经添加了相同的密钥."

Question

我正在尝试安装Microsoft.Bcl.Build 1.0.14

努特回归

Installing 'Microsoft.Bcl.Build 1.0.14'. Successfully installed 'Microsoft.Bcl.Build 1.0.14'. Adding 'Microsoft.Bcl.Build 1.0.14' to LeadTracker.Calendar. Uninstalling 'Microsoft.Bcl.Build 1.0.14'. Successfully uninstalled 'Microsoft.Bcl.Build 1.0.14'. Install failed. Rolling back... An item with the same key has already been added.

这也发生在json.net和其他软件包上.

我可以添加nancy和topshelf但不能添加json.net和bcl.

我在VS2012和2013中尝试过它.我也尝试卸载nuget并重新安装.我也尝试将nuget添加到空类库和空控制台应用程序中.始终返回相同的错误.

这也发生在json.net和其他软件包上.

我也试过没有包文件

任何想法最受赞赏.

这是命令和堆栈跟踪

Answer 1

检查你的packages.configInside,检查你要安装的软件包.也许已经有一些参考,这避免了你可以安装新的.

如果找到引用,请从packages.config中删除引用并尝试再次安装该包.

有时我发生在package.config中是一些旧的引用,即使从Nuget包管理器中删除包后仍然留在那里.

如果没有,您可以删除整个packages.config,然后如果您可以选择让Nuget下载软件包,那么在构建解决方案时,将再次下载软件包.

我希望这有帮助

Answer 2

你的堆栈跟踪告诉故事,它 NuGet.NetPortableProfileTable.BuildPortableProfileCollection()失败了.简而言之,它迭代了一组PCL参考装配配置文件,并且不止一次地遇到相同的配置文件.这是一个非常强烈的提示,表明您的c:\program files (x86)\reference assemblies\microsoft\framework\.netportable目录内容已损坏.

有许多方法可以修复损坏:

• 如果你有一个积极的回忆来修改这个目录,比如复制文件,那么撤消你所做的.
• 最安全的方法是卸载所有 Visual Studio版本> = VS2010.然后手动清理目录,删除仍然存在的任何杂散文件.然后再次重新安装VS.
• 不那么安全但速度更快的方法是重命名 c:\ program files(x86)\ reference assemblies目录并安装多目标包.我不能保证成功.
• 您可以尝试自己查找副本并将其删除.目录结构如下所示:

Answer 3

看起来NuGet正在您的计算机上找到重复的可移植类库（PCL）配置文件。遗憾的是，没有在异常调用堆栈中记录密钥，这使事情变得容易。

您可以尝试Jon Skeet的PclPal程序，该程序可以列出PCL配置文件，并查看是否有重复的内容。

我还有另一个执行类似操作的MonoPcl程序。它指的是Mono，但可在Windows上使用。它使用NuGet源代码，因此将遇到与Visual Studio中相同的问题。但是，您应该能够修改代码以捕获异常，或进行一些额外的日志记录，以查看导致问题的重复PCL配置文件是什么。

Answer 4

还有另一条路径会产生此错误。以下是重现它的方法：

（1）从VS项目（项目1）创建nuget包。
(2) 在引用项目 1 的项目 2 中，安装项目 1 nuget 包。
(3) 安装会失败，出现“same key”错误。

解决方案是在安装 nuget 包之前简单地删除对项目 1 的引用。
