【问题描述】：
我正在尝试安装 Microsoft.Bcl.Build 1.0.14
nuget 返回
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.
json.net 和其他包也会发生这种情况。
我可以添加 nancy 和 topshelf，但不能添加 json.net 和 bcl。
我在VS2012和2013都试过了。我也试过卸载nuget并重新安装。我还尝试将 nuget 添加到一个空的类库和一个空的控制台应用程序中。总是返回相同的错误。
json.net 和其他包也会发生这种情况。
我也试过没有包文件
任何最受赞赏的想法。
这里是命令和堆栈跟踪

【问题讨论】：
-
您是否尝试删除 package.config 文件中的条目？
-
是的，并且在没有包文件的情况下进行了尝试。我已经更新了问题。
-
尝试从包管理器控制台窗口安装 NuGet 包。然后，如果在安装失败后运行“$error[0].exception.stacktrace”，您应该能够看到错误的完整异常调用堆栈。这可能会给我们一个更好的线索来了解它失败的原因和位置。
-
谢谢，已将堆栈跟踪添加到问题中
