Nuget的控制台版本在Package.config文件中出错

标签： .net visual-studio nuget nuget-package-restore

尝试在packages.config文件上运行nuget时，我得到以下输出：

Feeds used:

这是在Windows Server 2012上运行的，上面有jenkins。

我已尝试注册这里提到的dll：

https://docs.nuget.org/Release-Notes/Known-Issues

此命令：

regsvr32 "C:\Program Files (x86)\Common Files\microsoft shared\MSEnv\VsLangproj.olb"

上面的命令在我运行时没有失败，但它也没有解决问题。

这是我的packages.config文件：

`<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="NUnit" version="2.6.4" targetFramework="net452" />
  <package id="NUnitTestAdapter" version="2.0.0" targetFramework="net452" />
  <package id="Selenium.RC" version="2.53.0" targetFramework="net452" requireReinstallation="true" />
  <package id="Selenium.Support" version="2.53.0" targetFramework="net452" requireReinstallation="true" />
  <package id="Selenium.WebDriver" version="2.53.0" targetFramework="net452" requireReinstallation="true" />

  <package id="System.Threading.dll" version="1.0.2856.0" targetFramework="net35-client" />
</packages>`

重要的是要注意这是在Windows Jenkins Slave上运行的。我确实安装了Visual Studio，但现在它作为许可试用版运行。如果可能的话，我真的不想拥有许可证。另外，我从命令行运行nuget（在Jenkins模板中）。现在我直接指向nuget网站获取其软件包，但最终它将成为公司关系。

以下是Jenkins报告的错误：

 Call to NuGet
 Unknown option: '-encodedCommand'
 Finished calling Nuget

我相信encodedCommand语句是一个PowerShell的东西。

以下是详细的详细程度中从powershell运行的详细输出：

您可以尝试使用PowerShell在Windows Server 2012上使用powershell恢复您的软件包，并执行以下步骤，我已根据您身边的packages.config文件成功运行。

首先，创建一个脚本文件（.ps1），用于在解决方案根目录中找到packages.config文件，然后读取它们以运行nuget restore命令来恢复软件包。

#This will be the root folder of all your solutions - we will search all children of this folder
$SOLUTIONROOT = "C:\Projects\"
#This is where your NuGet.exe is located
$NUGETLOCATION = "C:\Projects\NuGet\NuGet.exe"

Function RestoreAllPackages ($BaseDirectory)
    {
        Write-Host "Starting Package Restore - This may take a few minutes ..."
        $PACKAGECONFIGS = Get-ChildItem -Recurse -Force $BaseDirectory -ErrorAction SilentlyContinue | 
            Where-Object { ($_.PSIsContainer -eq $false) -and  ( $_.Name -eq "packages.config")}
        ForEach($PACKAGECONFIG in $PACKAGECONFIGS)
            {
                Write-Host $PACKAGECONFIG.FullName
                $NugetRestore = $NUGETLOCATION + " install " + " '" + $PACKAGECONFIG.FullName + "' -OutputDirectory '" + $PACKAGECONFIG.Directory.parent.FullName + "\packages'"
                Write-Host $NugetRestore
                Invoke-Expression $NugetRestore
            }
    }

RestoreAllPackages $SOLUTIONROOT
Write-Host "Press any key to continue ..."
$x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")

其次，右键单击此文件以选择使用Powershell运行来执行脚本。然后它将根据找到的packages.config文件开始安装软件包。

此错误可能来自Nuget无法访问存储库。这发生在我身上，因为我没有通过命令行使用nuget配置设置设置我的代理设置： https://docs.nuget.org/consume/Command-Line-Reference#config-command
