Nuget无法安装特定版本

我能够设置自己的NuGet服务器（如上所述）。 服务器

Packages

文件夹包含多个版本的

MyPackage

，例如1.0.8.0和1.0.9.0。 当我以默认方式安装它时（没有指定版本），它将成功安装。但是当我明确地这样做的时候

Install-Package MyPackage -Version 1.0.9.0

以下消息出现错误：

安装程序包：找不到程序包“MyPackage”的版本“1.0.9.0”。 第1行字符：16

---

+安装包结果是

MyPackage.1.0.9.0.nupkg

和

MyPackage.1.0.9.0.symbols.nupkg

的共存导致NuGet崩溃。NuGet使用OData作为传输，在OData的深处，它无法序列化/反序列化两个包，抱怨“多个根节点”。

---

因此，我只是从

nuget pack

命令行中删除了

-symbols

，从而禁用了调试包生成，现在一切正常。

在尝试安装

EntityFramework

时遇到了类似的错误

原来

App.config

已经损坏，可能是在升级

目标框架时损坏的。现在有两个
，而
是一个新的根元素，因此错误
是多个根元素

腐败的：

手动固定版本：

在Package Manager控制台中发生错误后，请尝试使用以下命令查看异常的完整堆栈跟踪：
$error[0]。exception.stacktrace
。这应该指向NuGet中出现问题的地方。我也有同样的问题，但错误消息不同。软件包安装将失败，代码为1。从同一目录中删除符号包解决了此问题！还要确保同一个库中没有具有不同名称的副本。就我而言，文件夹中有一个松散的“MyPackage.X.X.nupkg副本”。
