带有 .NET Core1.1 构建的 Angular4.1 在 VSTS 托管的 VS2017 代理中失败

Question

我有一个位于 .NET Core 1.1 上的 Angular 4.1.1 应用程序，我最近从带有更新 3 的 VS2015 迁移到 VS2017。我的 csproj 在我的本地机器上构建并运行良好，但在通过其托管的 VS2017 代理在 VSTS 上设置构建时失败。

失败发生在“构建”步骤，这里是日志文件中指出原因的部分：

我在 VSTS 网站上注意到 Typescript 不包含在 VS2017 托管代理（以及最高 v2.0.6 的“托管”代理）支持的内容中，我认为这可能是上述原因错误，但是在我将应用程序迁移到 VS2017 之前，我已经能够在“托管”代理上成功运行构建，同时使用我现在尝试部署的相同版本 (2.2) 的打字稿..

如果有人能帮我解决这个问题，我将不胜感激。这是我的csproj供参考：

Answer 1

我最近设置了一个类似的构建并遇到了同样的问题。我能够通过为“dotnet restore”添加一个 .NET Core 步骤来解决它。

Answer 2

改用 Microsoft.TypeScript.MSBuild 2.3.3。 （2.2.2 有问题）。

这是我的csproj（不需要添加Microsoft.TypeScript.Compiler包）

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup Label="Globals">
    <SccProjectName>SAK</SccProjectName>
    <SccProvider>SAK</SccProvider>
    <SccAuxPath>SAK</SccAuxPath>
    <SccLocalPath>SAK</SccLocalPath>
  </PropertyGroup>

  <PropertyGroup>
    <TargetFramework>netcoreapp1.1</TargetFramework>
  </PropertyGroup>

  <PropertyGroup>
    <PackageTargetFallback>$(PackageTargetFallback);portable-net45+win8+wp8+wpa81;</PackageTargetFallback>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.0.0" />
    <PackageReference Include="Microsoft.AspNetCore" Version="1.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="1.1.2" />
    <PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="1.1.1" />
    <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="1.1.1" />
    <PackageReference Include="Microsoft.TypeScript.MSBuild" Version="2.3.3" />
    <PackageReference Include="Microsoft.VisualStudio.Web.BrowserLink" Version="1.1.0" />
  </ItemGroup>
  <ItemGroup>
    <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="1.0.0" />
  </ItemGroup>

</Project>

注意：根据我的测试，Typescript 2.1 可用于 Hosted VS2017 代理。
