Undefined method `each'

ruby-talk
1

Before I explain the issue I’m having I should preface it with some
important information. I’m a novice programmer at best and I’m new to
Ruby…

I’m trying to capture the authentication token from Nessus so I can use
it to run scans, reports, etc. I found the following code on the Nessus
site but I’m getting “undefined method `each' for
#<String:0x00000001458a10> (NoMethodError)” from a line of code near the
bottom (response.body.each do |line|). I’m using Ruby 1.9.1 running on
Linux (Ubuntu 10.04). Any insight you can provide would be much
appreciated!

ruby 1.8 had String#each, ruby 1.9 does not. Use String#each_line
instead.

(However, strangely, IO#each still exists)

Hi
  It seem that the method "each" in String has been removed from version
1.9.*,you can see the build-in method declaration in string.c:

    rb_define_method(rb_cString, "each_line", rb_str_each_line, -1);
    rb_define_method(rb_cString, "each_byte", rb_str_each_byte, 0);
    rb_define_method(rb_cString, "each_char", rb_str_each_char, 0);
    rb_define_method(rb_cString, "each_codepoint",
rb_str_each_codepoint, 0);

There is no "each",use "each_line" or others instead.

Wow, I didn't expect that to be the issue. I'll give it a try with
"each_line". Thanks so much for your help!
