New-Object：术语New-Object不被识别为cmdlet的名称

Question

I want to configure high trusted app for app dev in SharePoint, and to do so, i need first to insert some commands in the powershell editor like :

$publicCertPath = "C:\Certs\HighTrustSampleCert.cer" 
$certificate = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2($publicCertPath)

I am using windows PowerShell on Windows Server 2012 R2 which includes Windows PowerShell 4 that includes by default the new-object cmd-let... I don't understand though, why doesn't my operating system recognize that command ... I don't stop having the following error : New-Object : The term 'New-Object' is not recognized as the name of a cmdlet.

When i open powerShell i get this :

*select :

The term 'Select-Object' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At C:\\Program Files\\Common Files\\Microsoft Shared\\Web Server Extensions\\15\\CONFIG\\POWERSHELL\\Registration\\SharePoint.ps1:1 char:16 + $ver = $host | select version + ~~~~~~ + CategoryInfo : ObjectNotFound: (Select-Object:String) [], Comma ndNotFoundException + FullyQualifiedErrorId : CommandNotFoundException Set-location : The term 'Set-location' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again At C:\\Program Files\\Common Files\\Microsoft Shared\\Web Server Extensions\\15\\CONFIG\\POWERSHELL\\Registration\\SharePoint.ps1:4 char:1 + Set-location $home + ~~~~~~~~~~~~ + CategoryInfo : ObjectNotFound: (Set-location:String) [], Comman dNotFoundException + FullyQualifiedErrorId : CommandNotFoundException*

I thought that was normal until today... does it have any relation with the error? And here is the hole (new-object) exception stack:

New-Object : The term 'New-Object' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:16 + $certificate = New-Object System.Security.Cryptography.X509Certificates.X509Cert ... + ~~~~~~~~~~ + CategoryInfo : ObjectNotFound: (New-Object:String) [], CommandN otFoundException + FullyQualifiedErrorId : CommandNotFoundException

ps: i want to mention that when i used enter-psSession and worked remotely, the command new-object was recognized but sharepoint commands (like Get-SPAuthenticationRealm) were no more recognized ...

Answer 1

It appears that your PowerShell installation is corrupted and needs to be repaired. The New-Object cmdlet is exported by the Microsoft.PowerShell.Utility module, which is one of the Core PowerShell modules and should be imported by default on all PowerShell installations.

Answer 2

This can be because the Registry key entry for PSModulesPath is not pre-filled with the default PowerShell Modules path.

$PSModulePath = Get-ItemProperty -Path "HKLM:SYSTEM\CurrentControlSet\Control\Session Manager\Environment" -Name "PSModulePath"

$newPSModulePath = $PSModulePath.PSModulePath + ";C:\Windows\System32\WindowsPowerShell\v1.0\Modules"

Set-ItemProperty -Path "HKLM:SYSTEM\CurrentControlSet\Control\Session Manager\Environment" -Name "PSModulePath" -value $newPSModulePath

Answer 3

这里没有任何验证，但我推进了Powershell遇到运行时错误导致它破坏其进程的假设。
