A collegue is trying to install a nuget package into a simple default c# web application. It fails almost instantly.
Is there an argument I can provide to Install-Package <some nuget package> in the Visual Studio Package Manager Console to get some verbose information to help debug why the installation fails?
Error Message:
An error occurred while retrieving package metadata for '' from source 'MyGet'.
Info:
Visual Studio: V2015
NuGet extension: 3.4.4.1321
Nuget package source: MyGet
Sample NuGet.config file found in the root directory of the solution:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
<add key="MyGet" value="https://www.myget.org/F/<our package>/api/v2" />
</packageSources>
</configuration>
For myself, I can install the package fine. In fact, we have 5 packages in this MyGet public repo and I just installed 2 of the packages, just then .. when I test this out (again) before I created this SO question.
Anyone have a suggestion, please?
As stated above, this is using the PACKAGE MANAGER CONSOLE, not the CLI.
Using the -verbosity detailed in the PMC this is what happens..
PM> install-package xunit -verbosity detailed
Install-Package : A parameter cannot be found that matches parameter name 'verbosity'.

Looks like you are running into http://blog.myget.org/post/2016/02/21/Two-of-my-packages-are-treated-as-one-Help!.aspx. There is a 0.7.0-dev and a 0.7-dev version of the package on the feed, which NuGet treats as the same version.
The solution is to remove one of these two packages.
