为什么Dir.glob在Rails控制台/运行器中不起作用？

Question

Dir.glob("*.jpg") {|_| puts 'hello'}

This works perfectly fine in IRB or a regular Rails script, but fails in Rails Console or a rails runner script. Which is irritating because I really need to use it. Google has no information on this that I can find. What's the deal?

Answer 1

Are there any JPG files in the root level of your app vs where you run ruby foo.rb . I don't have any in mine, but if I tweak your code to this:

Dir.glob("**/*.jpg") {|_| puts _}

I get all of my jpg assets like I'd expect.
