代码在本地构建但在构建定义中获取构建错误

Question

我编写了一个使用 entity framework 的项目，并且在本地运行良好。但是当我尝试运行使用 VSTS 进行自动构建时，我在运行ning 构建定义时出错。我知道它是由 Entity framework 引用引起的，但我无法找到根本原因。这是构建错误以供参考。

问题出在您使用本地引用的 .csproject 中的引用（它取自您硬盘中的 packages 文件夹）。显然，这在部署在服务器中时将不起作用。将其更改为 nugetpackages 路径。按照我在下面给出的格式更改所有参考的提示路径

$(NugetPackagesPath)\EntityFramework.6.1.1\lib\net45\Entity‌Framework.dll

您可以使用下面定义 NugetPackagesPath 的代码

<PropertyGroup>
    <!-- EnlistmentRoot is the base directory where all of the module root directories reside. --> 
    <EnlistmentRoot>$(MSBuildThisFileDirectory)</EnlistmentRoot>
    <EnlistmentRoot Condition="'$(EnlistmentRoot)' != ''">$([System.IO.Path]::GetFullPath('$(EnlistmentRoot)'))</EnlistmentRoot>
    <EnlistmentRoot Condition="'$(EnlistmentRoot)' != '' and !HasTrailingSlash('$(EnlistmentRoot)')">$(EnlistmentRoot)\</EnlistmentRoot>
</PropertyGroup>
<PropertyGroup>
    <!-- NuGetPackagesPath is the base directory for all nuget packages. --> 
    <NuGetPackagesPath>$(EnlistmentRoot)Ref\Packages</NuGetPackagesPath>
    <NuGetPackagesPath Condition="'$(NuGetPackagesPath)' != ''">$([System.IO.Path]::GetFullPath('$(NuGetPackagesPath)'))</NuGetPackagesPath>
    <NuGetPackagesPath Condition="'$(NuGetPackagesPath)' != '' and !HasTrailingSlash('$(NuGetPackagesPath)')">$(NuGetPackagesPath)\</NuGetPackagesPath>
</PropertyGroup>
