Cannot run rails generate administrate:install

Created by: nguyen7thai

Hi All,

I'm trying gem administrate but I encounter the problem when running the command generate administrate:install.

As I investigated, the problem is because of this lines of code in namespace.rb:

def resources
    namespace_controller_paths.uniq.map do |controller|
      controller.gsub(/^#{namespace}\//, "").to_sym
    end
end

Its returned value includes the symbol that is created from empty string :"" . Does anyone encounter this error?

Here's the backtrace:
