问题描述
我在Azure Pipelines中遇到了一个问题，我的回购中有一个本地NuGet软件包，我希望将其与所有其他NuGet软件包（通常都是从nuget.org拾取）一起包含在管道构建中。我的项目基于ASP.NET Core，更具体地说，它是Blazor服务器端Web应用程序。
本地NuGet软件包“ Breeze.Sharp.0.9.6.nupkg”存储在我的存储库中，位于： MySolution / packages
正在发生的事情是nuget.org软件包在管道中恢复正常，但是在尝试找到我的本地NuGet软件包位置并抛出以下错误时失败了：
1>/usr/share/dotnet/sdk/3.1.402/NuGet.targets(128,5): error : The local source '/home/vsts/work/1/Nuget/MySolution/packages' doesn't exist. [/home/vsts/work/1/s/MySolution/MySolution.sln]

我的最初想法与其他人相同... AH 路径一定不正确！但是...在尝试各种不同的路径以进入packages文件夹以提取我的本地NuGet软件包之后，我似乎无法使其正常工作。
为帮助您，我的配置文件在下面。
azure-pipelines.yml：
trigger:
- master
pool:
vmImage: 'ubuntu-latest'
variables:
buildConfiguration: 'Release'
steps:
- task: NuGetToolInstaller@1
displayName: 'Use NuGet 4.9.1'
inputs:
versionSpec: 4.9.1
- task: DotNetCoreCLI@2
displayName: 'Restore NuGet Packages'
inputs:
command: 'restore'
projects: '**/*.sln'
FeedsToUse: 'config'
nugetConfigPath: 'MySolution/NuGet.Config'
- task: DotNetCoreCLI@2
displayName: 'Build web project'
inputs:
command: 'build'
projects: $(SolutionPath)
NuGet.Config：
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<clear />
<add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
<add key="LocalPackages" value="MySolution/packages" />
</packageSources>
</configuration>
我一直在讨论的问题是“ LocalPackages”元素，我认为这可能是问题所在，因此一直在尝试各种路径组合以缩小范围-但没有运气-这让我觉得这 可能 是个红鲱鱼，但是你永远不知道我会做些愚蠢的事！
我知道这里可以遵循一些最佳实践，例如创建我自己的NuGet软件包的Artifacts提要以实现可维护性，但这对我来说将是一个精炼阶段，此刻我的重点只是简单地处于构建状态的管道准备就绪，可以进行部署和测试。
对此有任何帮助或指导或我可以尝试解决的问题，将不胜感激！
让我知道是否需要更多具体信息，我可以提供！
谢谢。
解决方法
是导致问题的本地软件包路径。您应该将值设置为<add key="LocalPackages" value="../s/MySolution/packages" />
如果检查dotnet还原任务日志，则会发现已创建一个临时配置，并且还原任务正在使用此临时配置文件。见下文。
因此，您在nuget.config文件中指定的LocalPackages路径相对于临时配置文件夹/home/vsts/work/1/Nuget。
由于您的项目已克隆到文件夹/home/vsts/work/1/s（即$(system.defaultworkingdirectory)）中。您应该指定LocalPackages路径，如下所示：
<add key="LocalPackages" value="../s/MySolution/packages" />
