带有 NuGet 上游源的 Azure DevOps Artifacts 源的安装包失败

Question

问题

我正在尝试从公共存储库安装软件包。我想使用 PackageSource External。这是一个 Azure DevOps 工件源，使用 NuGet 库 配置为 Upstream source。由于 NuGet Gallery 是上游源，我对包的请求应该通过 Artifacts 并由上游源完成，但它会出错并说不匹配。

另一方面，如果我使用直接指向 NuGet Gallery 的 PackageSource 提交相同的请求，它就可以工作。 Artifacts 中的上游源功能会被破坏吗？

上游源功能在我这边运行良好。但是，我在安装包期间没有收到此推广信息。

The package(s) come(s) from a package source that is not marked as trusted.

这似乎与您的本地安全设置有关。不知道如何启用或禁用。不过根据你的描述和情况。在我看来，我想知道您在使用 Azure DevOps Artifacts 包源安装包期间是否有跳转。

由于与直接连接 NuGet Gallery 不同，您需要先访问 Azure DevOps Artifacts Feed，然后通过上游源来获取该包。您无法选择信任信息，它选择默认（默认为“否”）。最后，您无法安装该软件包。

您可以关闭本地安全设置并重试，这可能会奏效。如果由于政策原因，您无法将其关闭。

作为一种解决方法，您可以在关闭上游的情况下创建需求提要，并将您的包上传到提要中作为包源。

所以在做了一些额外的测试之后，我确实发现使用 nuget.exe CLI 可以在 Install-Command cmdlet 失败的地方工作。

不幸的是，我仍然不完全确定为什么会发生这种行为。

下面是我的Install-Package版本

>Get-Command -name 'Install-Package'

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Cmdlet          Install-Package                                    1.4.3      PackageManagement

还有我的nuget.exe版本

>nuget
NuGet Version: 5.2.0.6090

最后，这是 nuget.exe 命令成功的输出。
