c# - 进程 'C:\hostedtoolcache\windows\dotnet\dotnet.exe' 失败，退出代码 1

Question

我的问题是我在.net core 2.2中创建了一个项目，问题是我尝试使用azure pipelines部署它，但是当使用dotnet Restore时它不断失败并结束构建。

它返回的错误如下:

2020-11-21T20:17:30.4639428Z ##[error]**Error: The process 'C:\hostedtoolcache\windows\dotnet\dotnet.exe' failed with exit code 1**

2020-11-21T20:17:30.4652823Z ##[error]**Packages failed to restore**

2020-11-21T20:17:30.4655465Z **Info: Azure Pipelines hosted agents have been updated to contain .Net Core 3.x (3.1) SDK/Runtime along with 2.1. Unless you have locked down a SDK version for your project(s), 3.x SDK might be picked up which might have breaking behavior as compared to previous versions.**

我尝试安装版本2.2以在恢复之前的过程中使用，我尝试使用nuget.config和global.json。我将我用过的.yml留在这里，看看是否有人可以提供我伸出一只手。

steps:
- task: UseDotNet@2
  displayName: 'Use .NET Core sdk 2.2.x'
  inputs:
    version: 2.2.x
    includePreviewVersions: true
    performMultiLevelLookup: true

  displayName: 'dotnet restore'
  inputs:
    command: restore
    projects: '**/*.csproj'

- task: NuGetToolInstaller@0
  displayName: 'Use NuGet 4.4.1'
  inputs:
    versionSpec: 4.4.1
    checkLatest: true

- task: NuGetCommand@2
  displayName: 'NuGet restore'
  inputs:

Answer 1

我已经使用以下 yaml 文件对 .net core 2.2 项目进行了测试，并获得了成功的结果。

trigger:
- master

pool:
  vmImage: 'windows-latest'

steps:
  - task: UseDotNet@2
    inputs:
      version: '2.2.x'
      includePreviewVersions: true
      performMultiLevelLookup: true
  - task: DotNetCoreCLI@2
    inputs:
      command: 'restore'
      projects: '**/*.csproj'

为了缩小问题范围，我建议您:

1. 创建一个简单的 .net core 2.2 项目并推送到 DevOps，为此项目创建管道以查看是否可以重现此问题。
2. 将项目克隆到本地，并在本地运行 dotnet restore 命令查看结果如何。
