为什么即使指定了 --ignore-failed-sources，dotnet-ef 安装也会失败

问题描述 投票：0回答：1

我正在通过 Azure DevOps Pipelines 构建一个 .NET 6 项目。其中一个步骤是安装实体框架工具，以便后续步骤可以生成 SQL 迁移脚本。

但是，安装步骤失败并出现 

401 Unauthorized
异常，即使该包似乎是在公共 
nuget.org
源中找到的。由于指定了 
--ignore-failed-sources
，即使私人提要无法找到包，至少有一次命中也应该标志着整个调用成功。

我什至尝试添加 

--version 6.*
，因为该项目位于 .NET 6 中，但调用的总体结果保持不变。

为什么我会遇到异常？如何解决这个问题？

Info: Azure Pipelines hosted agents have been updated and now contain .Net 5.x SDK/Runtime along with the older .Net Core version which are currently lts. Unless you have locked down a SDK version for your project(s), 5.x SDK might be picked up which might have breaking behavior as compared to previous versions. You can learn more about the breaking changes here: https://docs.microsoft.com/en-us/dotnet/core/tools/ and https://docs.microsoft.com/en-us/dotnet/core/compatibility/ .

如果当前工作目录中存在 NuGet 配置文件 (

nuget.config
)，在其中运行命令“
dotnet tool install
”或“
dotnet tool update
”，该命令将使用 
nuget.config默认情况下为
文件。因此，该命令还将验证 
nuget.config
 文件中设置的包源（提要）的凭据。如果 
nuget.config
 文件设置了私有包源，则运行该命令时可能会收到 401 Unauthorized 错误。

要避免此问题，您可以尝试以下方法之一：

  1. 将命令的工作目录更改为另一个不包含任何 

    nuget.config
    文件的目录。这样，任务就会在指定的目录下运行命令。指定的目录仅适用于当前 
    DotNetCoreCLI@2
     任务，不能更改其他任务的工作目录。

    - task: DotNetCoreCLI@2
  displayName: 'dotnet custom'
  inputs:
    command: custom
    custom: tool
    arguments: 'install dotnet-ef --global --version 6.*'
    workingDirectory: '$(Agent.BuildDirectory)'

  2. 在运行之前添加 

    NuGetAuthenticate@1
    任务，运行命令“
    dotnet tool install
    ”或“
    dotnet tool update
    ”以生成可以访问私有包源的凭据。

    • 对于当前 Azure DevOps 组织内的源，此任务将自动构建凭据。
    • 对于当前 Azure DevOps 组织外部的源，您需要在此任务上提供 NuGet 服务连接以连接到外部源。此任务支持指定多个 NuGet 服务连接。
    - task: NuGetAuthenticate@1
  displayName: 'NuGet Authenticate'
  inputs:
    nuGetServiceConnections: 'Connection_outsideFeed01, Connection_outsideFeed02'
