PowerShell PSCX 读取存档:无法绑定参数...问题
我遇到了一个问题,我似乎无法使用通过 PowerShell 社区扩展 (v2.0.3782.38614) 提供的 Read-Archive cmdlet 来解决这个问题。
这是一个用于展示我遇到的问题的缩减示例:
$mainPath = "p:\temp"
$dest = Join-Path $mainPath "ps\CenCodes.zip"
Read-Archive -Path $dest -Format zip
运行上面的代码会产生以下错误:
Read-Archive : Cannot bind parameter 'Path'. Cannot convert the "p:\temp\ps\CenCodes.zip" value of type "System.String" to type "Pscx.IO.PscxPathInfo".
At line:3 char:19
+ Read-Archive -Path <<<< $dest -Format zip
+ CategoryInfo : InvalidArgument: (:) [Read-Archive], ParameterBindingException
+ FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Pscx.Commands.IO.Compression.ReadArchiveCommand
如果我不使用 Join-Path 来构建传递给 Read-Archive 的路径,它就可以工作,如本示例所示:
$mainPath = "p:\temp"
$path = $mainPath + "\ps\CenCodes.zip"
Read-Archive -Path $path -Format zip
上面的输出:
ZIP Folder: CenCodes.zip#\
Index LastWriteTime Size Ratio Name ----- ------------- ---- ----- ----
0 6/17/2010 2:03 AM 3009106 24.53 % CenCodes.xls
更令人困惑的是,如果我比较上面两个读取存档示例中作为 Path 参数传递的两个变量,它们看起来相同:
这...
Write-Host "dest=$dest"
Write-Host "path=$path"
Write-Host ("path -eq dest is " + ($dest -eq $path).ToString())
输出...
dest=p:\temp\ps\CenCodes.zip
path=p:\temp\ps\CenCodes.zip
path -eq dest is True
任何人都对为什么第一个示例有任何想法抱怨但第二个工作正常吗?
I'm running across a problem I can't seem to wrap my head around using the Read-Archive cmdlet available via PowerShell Community Extensions (v2.0.3782.38614).
Here is a cut down sample used to exhibit the problem I'm running into:
$mainPath = "p:\temp"
$dest = Join-Path $mainPath "ps\CenCodes.zip"
Read-Archive -Path $dest -Format zip
Running the above produces the following error:
Read-Archive : Cannot bind parameter 'Path'. Cannot convert the "p:\temp\ps\CenCodes.zip" value of type "System.String" to type "Pscx.IO.PscxPathInfo".
At line:3 char:19
+ Read-Archive -Path <<<< $dest -Format zip
+ CategoryInfo : InvalidArgument: (:) [Read-Archive], ParameterBindingException
+ FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Pscx.Commands.IO.Compression.ReadArchiveCommand
If I do not use Join-Path to build the path passed to Read-Archive it works, as in this example:
$mainPath = "p:\temp"
$path = $mainPath + "\ps\CenCodes.zip"
Read-Archive -Path $path -Format zip
Output from above:
ZIP Folder: CenCodes.zip#\
Index LastWriteTime Size Ratio Name ----- ------------- ---- ----- ----
0 6/17/2010 2:03 AM 3009106 24.53 % CenCodes.xls
Even more confusing is if I compare the two variables passed as the Path argument in the two Read-Archive samples above, they seem identical:
This...
Write-Host "dest=$dest"
Write-Host "path=$path"
Write-Host ("path -eq dest is " + ($dest -eq $path).ToString())
Outputs...
dest=p:\temp\ps\CenCodes.zip
path=p:\temp\ps\CenCodes.zip
path -eq dest is True
Anyone have any ideas as to why the first sample gripes but the second one works fine?

我在 PSCX CodePlex 主页上的问题跟踪器中创建了一个项目。显然这是 PscxPathInfo 当前的已知问题。 (请参阅 PSCX 问题跟踪器中的项目 #28023)。
解决方法是这样做:
归功于 CodePlex 上的 r_keith_hill 的特定解决方法。
I created an item in the issue tracker on the CodePlex home of PSCX. Apparently this is a current known issue with PscxPathInfo. (See item #28023 in the PSCX Issue Tracker).
A work around is to do this:
Credit to r_keith_hill on CodePlex for that particular work around.
