I see now there is 1 line i missed.
"Must have nmap already installed"
Would the above error have been caused because I didn't?

@DanRobinsonHPE confirmed looks like there is an issue on 5.1, it works just fine on Powershell 7, looks to be a packaging issue with the newest version.

In powershell 7.2.2 its not working either:

@bust4rhymes this module does not install nmap for you, you have to supply it.

@JustinGrote it looks like you have an extra PoshNmap in the load path on line 20 of the manifest file. It should go $PSScriptRoot\lib\Newtonsoft.Json-net40-client.dll. I removed it and the module loaded as expected.

Found the same - and now I run into

PS C:\windows\system32> Invoke-Nmap www.google.com
ConvertFromXml : Method invocation failed because [Newtonsoft.Json.JsonConvert] does not contain a method named
'SerializeXmlNode'.
At C:\Program Files\WindowsPowerShell\Modules\PoshNMap\0.6.1\Public\ConvertFrom-NmapXML.ps1:41 char:26

Trying some work arounds got it to work eventually - now I get

@securatodd what version of Powershell are you running? It's only meant for 5.1+

@securatodd what version of Powershell are you running? It's only meant for 5.1+

Current Version I am running in is 5.1.17763.2867

[JustinGrote]

Thanks, I'll try to investigate when I get time but unfortunately I have very little bandwidth for my community repos at the moment. Sorry, it is what it is :/

i'm having the same problem with Powershell 7.4.0

In the latest version did you export/alias the functions properly?
I'm going to go check.

[JustinGrote]

Works for me on 7.4, fresh install.

Do ipmo poshnmap -passthru |% exportedcommands to verify
