Question

我正在尝试使用包管理器控制台安装此包。

https://www.nuget.org/packages/WebDriver.IEDriverServer.win32/

包裹经理：2.8.50313.31

install.ps1

param($installPath, $toolsPath, $package, $project)

$file = Join-Path (Join-Path $toolsPath '..\content') 'IEDriverServer.exe' | Get-ChildItem

$project.ProjectItems.Item($file.Name).Delete()

$project.ProjectItems.AddFromFile($file.FullName);
$pi = $project.ProjectItems.Item($file.Name);  # this line fails
$pi.Properties.Item("BuildAction").Value = [int]2;
$pi.Properties.Item("CopyToOutputDirectory").Value = [int]2;

错误：

Exception calling "Item" with "1" argument(s): "The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))"
At C:\dev\Projects\AttachmentUnitTests\packages\WebDriver.IEDriverServer.win32.2.42.0\tools\install.ps1:9 char:1

ProjectItems.AddFromFile api会返回一个项目 ProjectItems |选择名称不会。

我是另一个用于安装Selenium IEDriver的NuGet软件包的所有者。

我试图在我的NuGet包项目中解决此问题，并立即发布测试版。

https://www.nuget.org/packages/Selenium.WebDriver.IEDriver/2.42.0.1-beta

我的策略是使用Microsoft.Build类库，并在检测到此问题的情况时将CSPROJ视为MSBuild脚本XML而不是EnvDTE对象模型。

顺便说一句，我的NuGet包＆＃34; Selenium.WebDriver.IEDriver＆＃34;不包含IEDriverServer.exe。它只是在构建过程中从orignal发布点下载驱动程序。这意味着您需要访问Internet才能成功构建项目。

问题是将packages文件夹放在与csproj文件相同的目录中。

最初的设置是：

C:\DEV\ATTACHMENTUNITTESTS\
+---.nuget\
+---AttachmentUnitTests.sln
+---AttachmentUnitTests.csproj
+---packages\
    \---WebDriver.IEDriverServer.win32.2.42.0\

AttachmentUnitTests.csproj有不正确的 ItemGroup条目

<ItemGroup>
  <Content Include="packages\WebDriver.IEDriverServer.win32.2.42.0\content\IEDriverServer.exe" />
</ItemGroup>

更改结构以便CSPROJ在其自己的子目录中使问题消失。

C:\DEV\ATTACHMENTUNITTESTS\
+---.nuget\
+---AttachmentUnitTests.sln
+---AttachmentUnitTests\
|   +---Packages.config
|   \---AttachmentUnitTests.csproj
+---packages\
    \---WebDriver.IEDriverServer.win32.2.42.0\

AttachmentUnitTests.csproj有正确 ItemGroup条目

<ItemGroup>
  <Content Include="..\packages\WebDriver.IEDriverServer.win32.2.42.0\content\IEDriverServer.exe">
    <Link>IEDriverServer.exe</Link>
    <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
  </Content>
</ItemGroup>

此问题的解决方法是将CSPROJ移动到不包含Packages文件夹的sufolder。

我能够使用修改后的install.ps1让原始安装正常工作，这说明问题是因为

param($installPath, $toolsPath, $package, $project)

$file = Join-Path (Join-Path $toolsPath '..\content') 'IEDriverServer.exe' | Get-ChildItem
# IEDriverServer.exe is copied to the project root because it's in the content folder of the nupkg
# this line will always work because the file exists as a copy in the root of the project
$project.ProjectItems.Item($file.Name).Delete()

# now we want to re-add it as a linked item in the Packages folder
$pi = $project.ProjectItems.AddFromFile($file.FullName);
# reference the original item returned by AddFromFile, no need to go looking again
#$pi = $project.ProjectItems.Item($file.Name);
$pi.Properties.Item("BuildAction").Value = [int]2; 
#2 = prjBuildActionContent - The file is included in the Content project output group

...并修改了uninstall.ps1

param($installPath, $toolsPath, $package, $project)

# original code didn't work when packages\ is in same folder as csproj
#$file = Join-Path (Join-Path $toolsPath '..\content') 'IEDriverServer.exe' | Get-ChildItem
#$project.ProjectItems.Item($file.Name).Delete()

# don't show nasty red warnings.
$ErrorActionPreference = "SilentlyContinue"
# create a variable with null value
$pi = $null
# does
$pi = $project.ProjectItems.Item($file.Name)
if $pi -eq $null then $pi = $project.ProjectItems.Item("packages").ProjectItems.Item($package).ProjectItems.Item("content").ProjectItems.Item("IEDriverServer.exe")
if $pi -ne $null then $pi.Delete()

为什么这个Nuget安装脚本失败了？
