在构建服务器上运行构建的位置似乎有问题：

It looks like a problem with the location where the build is running on the build server:

C：\TFS Build Agent\agent\agent\agent\worker\tools\NuGet.exe包C：\TFS
构建Agent\agent_work\2\s\WebFeatureService.csproj -OutputDirectory
C：\TFS构建Agent\agent_work\2\s-Properties Configuration = Debug

C:\TFS Build Agent\agent\agent\worker\tools\NuGet.exe pack C:\TFS Build Agent\agent_work\2\s\WebFeatureService.csproj -OutputDirectory C:\TFS Build Agent\agent_work\2\s -Properties Configuration=Debug

由于CSPROJ文件路径周围缺少引号，因此这在服务器上可能很麻烦。

This is probably struggling on the server due to the lack of quotes around the path to the CSPROJ file.

在我的VSTS托管的构建代理上，所有操作都在 C：\a\1\s\ ... 。

On my VSTS hosted build agent everything is executing in C:\a\1\s\....

尝试更改代理的本地安装。

Try changing the local installation of the Agent.

如果发现是它，让我知道，我想我知道需要做些什么来解决它。

If that turns out to be it, let me know, I think I know what needs to be done to fix it.
