Environment data

PowerShell 6.2.1 on Debian Stretch
v0.14.0

You need to build c-sharp part of the project if you want to run it from source. Or you can simply get it from psgallery with Import-Module -Scope CurrentUser platyPS.

Does that work for Linux running PowerShell Core?

I have PlatyPS v0.14.0. I see the Markdown.MAML.dll file in the root of the module, but maybe Linux cannot use those out of the box?

[vors]

Yes, it works on linux. Here are CI builds https://travis-ci.org/PowerShell/platyPS/builds

[vors]

# Copy over PlatyPS and any PS module
docker copy C:\path\to\platyps platyps:/root/
docker copy C:\path\to\your\module platyps:/root/

You repro doesn't specify where you got the C:\path\to\platyps from.
You can do one of 2 things:

1. Build it yourself from sources, see linked instruction
2. Get it from gallery

Thanks for your help.

I was able to get it to work by:

• Copying the Markdown.MAML.dll and YamlDotNet.dll files into the platyps/src/platyps directory
• Importing the platyps module
• Running New-MarkdownHelp
