I am trying to install multiple packages with Chef's 'package' resource by using custom attributes. When I try:
package %w(python3 python3-pip) do
action :install
end
The above code works fine for me, but same code is giving error while trying with custom attributes.
Please have a look-
My recipe_code :
package %w(node['python']['pkg_name'] node['python-pip']['pkg_name']) do
action :install
end
Attribute_code :
default['python']['pkg_name'] = 'python3'
default['python-pip']['pkg_name'] = 'python3-pip'
Error log:

%w is a percent literal in Ruby, that creates an array from separate words in the brackets. Your first example works, because
%w(python3 python3-pip) == ['python3', 'python3-pip']
But this %w does not support string interpolation. Your second example is actually:
%w(node['python']['pkg_name'] node['python-pip']['pkg_name']) == ["node['python']['pkg_name']", "node['python-pip']['pkg_name']"]
See how your values are actually strings, not variables. If you need to use variables, use ordinary Array initialization, and not %w literal.
package [node['python']['pkg_name'], node['python-pip']['pkg_name']]
