ASP.NET 5 无法安装 ASP.NET 5 NuGet 包

【发布时间】：2015-08-16 09:20:40
【问题描述】：

我有一个名为 Boilerplate.Web.Mvc6 的 ASP.NET 5 NuGet 包。我无法在我的 ASP.NET 5 网站中引用 NuGet 包。这是我引用 "Boilerplate.Web.Mvc6": "1.0.11" 的 project.json 文件。

{
  // Omitted

  "dependencies": {
    "Microsoft.AspNet.Mvc": "6.0.0-beta6",
    "Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-beta6",
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta6",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-beta6",
    "Microsoft.AspNet.StaticFiles": "1.0.0-beta6",
    "Microsoft.AspNet.Tooling.Razor": "1.0.0-beta6",
    "Microsoft.Framework.Configuration.EnvironmentVariables": "1.0.0-beta6",
    "Microsoft.Framework.Configuration.Json": "1.0.0-beta6",
    "Microsoft.Framework.Configuration.UserSecrets": "1.0.0-beta6",
    "Microsoft.Framework.Logging": "1.0.0-beta6",
    "Microsoft.Framework.Logging.Console": "1.0.0-beta6",
    "Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.0.0-beta6",
    "Newtonsoft.Json": "7.0.1",
    "System.Runtime": "4.0.20-beta-23109",
    "Boilerplate.Web.Mvc6": "1.0.11"
  },

  // Omitted
}

当我在上面添加包时，项目中的引用显示错误，我在输出窗口中打印以下内容：

怎么了？

更新

这些是我的 NuGet 包源：

  1. nuget.org - https://api.nuget.org/v3/index.json
  2. 我的获取 - http://MyGet.org/aspnetmaster
  3. Microsoft .NET - https://www.nuget.org/api/v2/curated-feeds/microsoftdotnet/

更新 2

我运行 dnu restore --ignore-failed-sources 并得到以下输出，但它仍然找不到我的 NuGet 包。奇怪的是，我可以从我的 ASP.NET 5 项目中引用同一包的 1.0.10，但不能从 ASP.NET 5 类库中引用。

【问题讨论】：

  • 您可以发布您正在使用的所有 nuget 提要吗？您可以在 Tools->Options->Package Manager 下找到它
  • 我正在使用手机，所以无法查看，但请尝试取消选择除带有样板包的提要以外的所有提要，然后在包控制台中运行 Update-Package -reinstall Boilerplate.Web.Mvc6。
  • 供稿网址错误。应该是myget.org/F/aspnetmaster/api/v2

标签： nuget asp.net-core nuget-package


【解决方案1】：

这可能是一个 myget 错误。无论如何，我在 dnu 上打开了一个错误（请参阅here），并且还 ping 了 myget 的人。

问题是http://MyGet.org/aspnetmaster/FindPackagesById()?id='Boilerplate.Web.Mvc6' 在找不到包时返回 200 OK 和 HTML，我们尝试将其解析为 XML。

您可以将--ignore-failed-sources 传递给dnu restore 以解锁自己。

【讨论】：

  • 这似乎不起作用。请参阅我更新的问题。它应该去 NuGet，而不是我的包的 MyGet，但它无法从那里得到它。
  • 它查看所有提要，由于其中一个提要返回不正确的内容，因此失败。提要应包含 /F: myget.org/F/aspnetmaster/api/v2 。就像这里的提要一样：github.com/aspnet/MusicStore/blob/master/NuGet.Config#L6
  • 即使使用--ignore-failed-sources 选项？今天晚上我会尝试添加 v2 提要。我可以在 VS 选项中添加它还是需要一个 NuGet.config 文件？
  • 在 VS 中工作。顺便说一句，MyGet 的人修复了这个问题，所以你可能再也看不到崩溃了。但请务必使用正确的网址更新提要
  • 我更新了 VS -> 选项提要 URL。我不再收到异常，但我仍然收到Unable to locate Boilerplate.Web.Mvc6 &gt;= 1.0.11。它对你有用吗？
【解决方案2】：

我已尝试删除 project.lock.json 文件并重新打开 Visual Studio，这通常可以为我解决此问题。

我已经重试安装 1.0.11 版本的软件包，它神奇地工作了。由于以前的版本可以正常工作，并且我没有对项目或我的安装进行任何更改，我怀疑这是一个 NuGet 包载入问题。 NuGet 花了三天时间注册新版本的包。

【讨论】：

  • 删除project.lock.json解决了这里的问题。
