无法使用托管代理在 Visual Studio Team Services 上构建默认 ASP.Net Core Web 应用程序 (.NET Core)

【问题标题】：Unable to build default ASP.Net Core Web Application (.NET Core) on Visual Studio Team Services using Hosted Agent无法使用托管代理在 Visual Studio Team Services 上构建默认 ASP.Net Core Web 应用程序 (.NET Core)
【发布时间】：2016-11-03 12:31:01
【问题描述】：

已在 Visual Studio 2015 Update 3 中创建了一个新的 ASP.Net Core Web 应用程序 (.Net Core) 项目并将其签入到 Visual Studio Team Services git 存储库。我正在使用 .Net Core 和 ASP.Net Core 的发布版本。

我现在正在尝试使用 VSTS 构建系统使用基于本指南的构建定义来构建它：https://www.visualstudio.com/en-us/docs/build/apps/aspnet/aspnetcore-to-azure

但是，在dotnet restore 步骤中构建失败，日志如下所示（第一部分不包括在内，这是它开始失败的地方）。

我做错了什么？我是否需要以任何方式准备当前的托管代理才能使其与 ASP.Net Core 的 v1.0.0 版本一起使用？

【问题讨论】：

  • 我确实遵循了这些说明，但使用了托管代理替代方案。我们想使用托管代理，因为我们目前没有使用本地构建代理的选项。
  • 在常规选项卡上，您添加了什么“需求”？
  • 我没有添加任何需求。我应该添加什么？由于我使用的是托管代理，因此我似乎无法添加任何要求。另外，根据上面提到的文档，需求只需要添加到自定义构建代理中，但如果我错了，请纠正我。
  • 这看起来构建系统使用的是旧版本的 .Net Core SDK。你能把它升级到 1.0 吗？
  • 自 2016 年 7 月 13 日起，VSTS 托管的构建代理已更新为包括“.NET Core 1.0 with Preview 2 Tooling”。见blogs.msdn.microsoft.com/visualstudioalm/2016/07/13/…

标签： asp.net-core azure-devops project.json dotnet-cli


【解决方案1】：

您应该像这样替换 project.json 中的“工具”部分：

    "tools": {
    "BundlerMinifier.Core": "2.1.258",
    "Microsoft.AspNetCore.Razor.Tools": {
      "version": "1.0.0-preview2-final",
      "imports": [
        "netstandard1.6"
      ]
    },
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": {
      "version": "1.0.0-preview2-final",
      "imports": [
        "netstandard1.6"
      ]
    },
    "Microsoft.EntityFrameworkCore.Tools": {
      "version": "1.0.0-preview2-final",
      "imports": [
        "netstandard1.6"
      ]
    },
    "Microsoft.Extensions.SecretManager.Tools": "1.0.0-preview2-final",
    "Microsoft.VisualStudio.Web.CodeGeneration.Tools": {
      "version": "1.0.0-preview2-final",
      "imports": [
        "portable-net45+win8+wp8+wpa81",
        "netstandard1.6"
      ]
    }
  },

部分包需要导入netstandard1.6 但是Microsoft.VisualStudio.Web.CodeGeneration.Tools 需要netstandard1.6 和portable-net45+win8+wp8+wpa81

【讨论】：

  • 太好了，这帮助我摆脱了大部分错误。但是对于其他包我仍然会遇到相同的错误，其中一些在project.json 中没有明确说明，例如Microsoft.DotNet.ProjectModel.Loader。我怎样才能找到解决这些问题的方法？
  • 我也遇到了 Microsoft.DotNet.ProjectModel.Loader 的错误，但在我的情况下，按照 neodim 的回答中所述替换工具部分为我解决了这个问题。
  • 作为一个侧节点，您应该不再需要使用 preview2 导入。尝试清理缓存 (nuget.exe locals -clear all)
【解决方案2】：

我在使用 VSTS 中的托管构建代理时遇到了与 dotnet restore 相同的问题。根据@svick 的评论，我运行dotnet --version 来检查托管代理上安装的内容。到今天为止，它仍然是1.0.0-preview1-002702，而不是1.0.0-preview2-003121 的引用版本。

托管构建代理的官方软件可以在 https://www.visualstudio.com/en-us/docs/build/agents/hosted-pool 找到。特别是，请注意它仍然显示Visual Studio 2015 Update 2。希望这会很快更新。
