无法从 Azure DevOps Artifact Feed 访问 Chocolatey 包

Question

流动代码已推送到 Azure DevOps Artifacts Feed：

schily-cdrtools

使用 nuget.exe 推送 nuget 包并下载工作没有问题：

nuget.exe push -Source "cdrtools-artifacts" -ApiKey AzureDevOps schily-cdrtools.3.2.1.nupkg

nuget.exe install -Source "cdrtools-artifacts" schily-cdrtools 

但是，尝试使用 Chocolatey 注册此源会导致使用 v2 或 v3 nuget 注册时出现 404 错误：

choco source add -n=schily-artifacts `
>>    -s="https://flapjacks.pkgs.visualstudio.com/_packaging/schily-artifacts/nuget/v3/index.json" `
>>    -u="xxxxxxxx" -p="xxxxxxxxxxx"

 Error retrieving packages from source 'https://flapjacks.visualstudio.com/_packaging/schily-artifacts/nuget/v3/index.json':
 The remote server returned an error: (404) Not Found.
 schily-cdrtools not installed. The package was not found with the source(s) listed.
 Source(s): 'https://flapjacks.visualstudio.com/_packaging/schily-artifacts/nuget/v3/index.json'
 NOTE: When you specify explicit sources, it overrides default sources.
 If the package version is a prerelease and you didn't specify `--pre`,
 the package may not be found.
 Please see https://chocolatey.org/docs/troubleshooting for more
 assistance.

...以及使用 v2 时相同的 404 错误：

choco source add -n=schily-artifacts `
>>    -s="https://flapjacks.pkgs.visualstudio.com/_packaging/schily-artifacts/nuget/v2" `
>>    -u="xxxxxxxx" -p="xxxxxxx"

尝试使用 v2 注册列出未找到任何包，但是当使用 v3 运行 choco list 时，它会返回 404 错误。

最后，尝试使用 Install-Package 失败并出现凭据问题：

Install-Package schily-cdrtools
WARNING: Cannot access 'https://flapjacks.pkgs.visualstudio.com/_packaging/schily-artifacts/nuget/v3/index.json'. Are you missing 'Credential' parameter in the cmdlet?

Install-Package : No match was found for the specified search criteria and package name 'schily-cdrtools'. Try Get-Packa
geSource to see all available registered package sources.

], Exception

有什么想法没有我想念的吗？

我一直在使用以下内容作为指南：

Answer 1

PackageManagement cmdlet当前已损坏，因此使用不带-Credential参数的Install-Package将会失败。 您需要将-Credential参数添加到所有PackageManagement cmdlet中，以使其起作用。

如果我运行（ 完全 ）：

choco source add -n=schily-artifacts -s="https://flapjacks.pkgs.visualstudio.com/_packaging/schily-artifacts/nuget/v2" -u="xxxxxxxx" -p="xxxxxxxxxxx"

然后我得到：

Chocolatey v0.10.15
Added schily-artifacts - https://flapjacks.pkgs.visualstudio.com/_packaging/schily-artifacts/nuget/v2 (Priority 0)

Chocolatey会在您使用Feed之前对其进行验证：

choco list --source=schily-artifacts
Chocolatey v0.10.15

这是我所期望的（因为凭据无效）。 因此，我不确定添加源时您的错误来自何处。

Answer 2

无法从Azure DevOps Artifact Feed访问Chocolatey程序包

根据该指南中的步骤创建示例后，我无法重现此问题。 但我想为您提供一些疑难解答：

1. 检查您的Chocolatey版本，我的是Chocolatey v0.10.15 。
2. 添加名为源的Chocolatey Azure DevOps Feed时，请使用PAT代替密码。
3. 使用管理员运行命令行。

4. 命令行应该是完整的，并且不需要分支，例如：

    choco source add -n=MyCustomFeed -s="https://pkgs.dev.azure.com/<MyOrgName>/_packaging/<FeedName>/nuget/v2" -u="MyAccount.com" -p="PAT" 

我的测试结果：

希望这可以帮助。

另一种使用Credential Provider的方法，是在github.com/chocolatey/choco/issues/1721中发布的脚本的略微修改版本（最后几行更改为使用choco而不是nuget命令）。

该脚本运行凭据提供程序（它会提示您登录 Azure DevOps 并自动生成 PAT）。 返回的 PAT 与Leo Liu 的回答中的 choco 命令一起使用
