[英]Why nuget from VSTS nuget feed wants to install the same package multiple times and throwing error?
我在Azure中使用Durable Function App实现了REST Api,该应用程序使用了netstandard2.0
,并且在该解决方案中还有其他类库也使用netstandard2.0
。 其中之一是合同项目。
还有另一种解决方案,其中为此解决方案放置了UAT测试。 原因是Specflow仍不适用于.Net Core
,仅适用于.Net Framework
。 能够测试Api,我需要Api的合同。 这就是为什么我需要包括REST Api解决方案合同项目(这是netstandard2.0
)的原因。 此依赖关系由nuget管理。
当我想在Specflow项目(使用.Net Framework 4.7.1
)中安装Contracts软件包(使用netstandard2.0
)时,出现以下错误。
我试过的
netstandard2.0
nuget包。 我认为这是由于该项目使用.Net Framework 4.7.1
而不是Net Standard 2.0 Cannot create "C:\\...\\REST.Api.dll" because a file or directory with the same name already exists.
。 因此,我删除了解决方案软件包目录下的所有软件包。 我还删除了Visual Studio中的缓存。 但是,下次我启动Visual Studio并尝试安装软件包时,再次发生了相同的错误。 如何解决此问题? 我从.Net Framework 4.6
及更高版本和.Net Core
了解到,可以引用.Net Standard
库。
