Question

我有一个Visual Studio 2017解决方案，其中包括2个项目。一个项目使用.NET 4.7.1。另一个项目使用.NET Core。我对在VSTS中自动构建.NET 4.7.1项目感兴趣。但是，此时，我的构建失败，并显示以下错误：

The nuget command failed with exit code(1) and error(System.AggregateException: One or more errors occurred. ---> System.InvalidOperationException: Cannot determine the packages folder to restore NuGet packages. Please specify either -PackagesDirectory or -SolutionDirectory.
   at NuGet.CommandLine.RestoreCommand.GetPackagesFolder(PackageRestoreInputs packageRestoreInputs)

Packages failed to restore

此失败发生在我的VSTS构建管道中的第一个任务期间。该任务使用以下属性定义：

Command: restore
Path to solution, packages.config, or project.json: MyNet471Project/MyNet471Project.csproj
Feeds to use: Feed(s) I select here - <My Private NuGet repo>
Disable local cache is not checked

我不明白为什么会遇到这个问题。我想念什么？

更新值得注意的是，我已经删除了解决方案级别的“ packages”目录和本地计算机上的“ bin”目录。当我在Visual Studio中重建解决方案时，Visual Studio会自动获取软件包并成功构建。

但是，如果我从命令行运行nuget restore MyNet471Project/MyNet471Project.csproj，则会收到与VSTS中看到的错误类似的错误。命令行中的错误显示：

Cannot determine the packages folder to restore NuGet packages. Please specify either -PackagesDirectory or -SolutionDirectory.

正在运行哪些Visual Studio自动还原软件包？

Answer 1

根据错误消息，看来packages.config所在的project.json或MyNet471Project.csproj文件没有。

在字段Path to solution, packages.config, or project.json:中尝试提供指向packages.config或project.json文件本身而不是MyNet471Project.csproj的路径，或者给出指向{{ 1}}存在于同一文件夹中。

Answer 2

我在“目标目录”属性中添加了一个值，并且它起作用了！

VSTS-System.InvalidOperationException：无法确定要还原NuGet软件包的文件夹。指定-PackagesDirectory或-SolutionDirectory
