Hello all,

I’m trying to use the powershell\_out command, but get an error while including the Chef::Mixin::PowerShellOut.

This is my recipe:  
Chef::Resource.send(:include, Chef::Mixin::WindowsArchitectureHelper)  
Chef::Resource.send(:include, Chef::Mixin::PowershellOut)

cmd = powershell\_out!(‘write-host Hello World’);  
Chef::Log::info(“cmd.stdout = #{cmd.stdout}”)  
Chef::Log::info(“cmd.stderr = #{cmd.stderr}”)

# And this is the error I get:

# Recipe Compile Error in c:/chef/cache/cookbooks/lan\_driver/recipes/default.rb

## NameError

uninitialized constant Chef::Mixin::PowershellOut

## Cookbook Trace:

Please note that there is no error at the first line (Chef::Resource.send(:include, Chef::Mixin::WindowsArchitectureHelper)), only at the second line.  
I added the first line just for debugging.

I use Chef version 11.12.8.

What do I miss here?

Thanks,  
Raanan.

Few months ago I ran into same issue and I was suggested on this forum to have a “library” file with following content:

class Chef  
class Resource  
include Chef::Mixin::PowershellOut  
end  
end

This helped me. Try that and see if it works for you.

Thanks

Hi Kapil,  
Thank for youe answer!

It didn’t work for me. The source of the error moved to the library instead of the recipe.  
See below:

Have you declared a dependency on the 'windows' cookbook in your  
metadata for lan\_driver?

# Hello Julian, Bingo! Indeed I missed the depends "windows" declaration in the metadata.rb file. When I added the dependency, I got the following error:

# Recipe Compile Error in c:/chef/cache/cookbooks/lan\_driver/recipes/default.rb

## NoMethodError

No resource or method named `powershell_out!' for `Chef::Recipe "default"'

## Cookbook Trace:

c:/chef/cache/cookbooks/lan\_driver/recipes/default.rb:15:in `from\_file'

## Relevant File Content:

c:/chef/cache/cookbooks/lan\_driver/recipes/default.rb:

8: #  
9:  
10:  
11:  
12: #Chef::Resource.send(:include, Chef::Mixin::WindowsArchitectureHelper)  
13: Chef::Resource.send(:include, Chef::Mixin::PowershellOut)  
14:  
15\>\> cmd = powershell\_out!('write-host Hello World');  
16: Chef::Log::info("cmd.stdout = #{cmd.stdout}")  
17: Chef::Log::info("cmd.stderr = #{cmd.stderr}")  
18:

But, when I changed the line  
Chef::Resource.send(:include, Chef::Mixin::PowershellOut) to Chef::Recipe.send(:include, Chef::Mixin::PowershellOut) it worked!

Thank you!
