Question

调用-VMScript
对象引用未设置为对象的实例。

最终来自： VMware.VimAutomation.ViCore.Impl.V1.VixHelper.GetVixVersion（）

在我的机器上，当指向操作系统是Linux风格的VMGuest时，Invoke-VMScript失败。
*另一位开发人员可以毫无问题地运行此脚本 *他和我匹配PowerCLI和Vix版本 *这不是身份验证问题 **我可以去他的机器，使用我的Windows凭据，脚本运行
**他可以来我的机器，使用他的Windows凭据和脚本抛出

C：\ run_a_bash_script.ps1：

$my_fullname_vmIpChangeLin_ps1        = ( $MyInvocation.MyCommand.Definition )
$my_dir_vmIpChangeLin_ps1            = ( Split-Path $my_fullname_vmIpChangeLin_ps1 )

import-module "$( $my_dir_vmIpChangeLin_ps1 )\libs\ooooops\ooooops.psm1" -force

$script = "ls"


try

}
catch
{
    $desc = (ooooops_describe_error -obj:$_)
    write-host $desc
}

运行脚本：

PS c:\> C:\run_a_bash_script.ps1

脚本结果：

该方法似乎不存在

这两个都返回$ null

write-host ( [VMware.VimAutomation.ViCore.Impl.V1.VixHelper] | Get-Member -MemberType:All | Where-Object { $_.Name -like "%ersion%" } | Format-Table | Out-String )

和

write-host ( [VMware.VimAutomation.ViCore.Impl.V1.VixHelper] | Get-Member -MemberType:All -Static | Where-Object { $_.Name -like "%ersion%" } | Format-Table | Out-String )

Windows Os，ControlPanel /程序/程序和功能

VMWare VIX 1.12.1.33347

PowerCLI版本/配置

Answer 1

我遇到了同样的问题。我的Invoke-VMScript无效。在深入研究之后，我发现我的vCenter服务器（在我的情况下是目标服务器）正在进行ipv6配置。我删除了ipv6配置并将其更改为ipv4配置。

我的问题得到了解决。

Answer 2

如下所述：
* http://www.virten.net/2013/06/run-scripts-in-linux-guests-by-using-vmware-tools/
* http://www.lucd.info/2012/01/01/will-invoke-vmscript-work/
* https://communities.vmware.com/message/2314207

问题是VIX库是32位，我使用64位Powershell运行脚本。

在64位操作系统上：
* Powershell 64位是默认的
* 32位Powershell的路径是：％systemroot％\ syswow64 \ windowspowershell \ v1.0 \

一个简单的powershell语句，用于测试powershell进程是32位还是64位：

 [Environment]::Is64BitProcess
