"Is a directory" error when it should not be a directory

(The "Resolved" answer has been deleted.) If it has been resolved, you should state what the problem was.
Perhaps the FileTest.readable?(path) statement was unnecessary.

The
• Find.find method enumerates files below the directory for arguments.Include the directory itself.
The
• FileTest.#readable? method returns whether or not you have read permission, so the directory also returns true.

I'm sorry, but I refactored it.

require "find"

Find.find("/Users/tamada/Desktop/Review Dev/Recipe Data Perspective Material/Test Data/recipe/") do | path | 
  ifFileTest.file?(path)
    open(path)do|f|
      puts f.read
    end
  end
end

List the points.

The
• Kernel#require method argument is library name only and is abbreviated with an extension (by contrast Kernel#load is required).
• The class method uses :: such as Find::find.Find.find is common (but it was an old notation in the recent book "Effective Ruby" ^^;)
Ruby style is to not use then in the
• if statement.
For IO-handling methods such as the
• Kernel#open method, Ruby is the way to use blocks instead of using them because you tend to forget to close them.
• p is a debugging-only method.Use puts for output (although it may still be in the middle of debugging).
I think it is better to use file.read/f.read as the argument for p/puts instead of using the
• variabletext.I think it's harder to make mistakes if there are fewer variables.
