Write Errors to Log File in Ruby

I am trying to capture errors, check for a /tmp directory and then write the error to a logfile in that directory, currently I get:
.rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/fileutils.rb:252:in `mkdir': Permission denied @ dir_s_mkdir - /temp
Here is my code:
require 'logger'
require 'tmpdir'
temp = Dir.tmpdir()
log = Logger.new File.open("#{temp}/error.log", 'w')
log.level = Logger::INFO
begin
rescue StandardError => e
log.error "Error - #{e}"
puts "For detailed error messages, see: #{temp}/error.log"
end
I believe this error is because I am attempting to do something I don't have permission to do, what I don't understand is there a clean way to achieve what I am attempting? Thanks in advance for any time spent on this issue.
I have edited this with my updated code that answers my question. Thanks for all your input.

You are lacking privileges. Why try to write in/temp, why not just/tmp? Create a directory somewhere where the user running the script has more privileges, not in root, or use/tmp. Or run your script withsudo.

Don't bother specifying the path for a temp directory. Just useDir.tmpdirand/orDir.mktmpdirand let Ruby do the lifting for you: ruby-doc.org/stdlib-2.5.3/libdoc/tmpdir/rdoc/Dir.html

To make it work and compatible with Windows:
require 'logger'
require 'tmpdir'
tmp = Dir.mktmpdir
log = Logger.new File.open(File.join(tmp, 'error.log', 'w')
log.level = Logger::INFO
begin
# your code here
rescue StandardError => e
log.error "Error - #{e}"
puts "For detailed error messages, see the file: /temp/error.log"
end

- You shouldn't create /tmp directory - this directory always exist.
- You should place
beginabove checking code, not below.
require 'logger'
require 'fileutils'
begin
log = Logger.new File.open('/tmp/error.log', 'w')
log.level = Logger::INFO
rescue StandardError => e
puts "Error - #{e}"
end

It's/tmp, not/tempthat should exist. Rescuing from opening a file which is supposed to be used for error logging and logging that error to the same file does not make sense.

@mrtriangle if you're trying to make your program compatible with both Windows and Unix, create your logs somewhere inside your application directory (or handle that in an OS-specific way).

@mrtriangle, on most Windows system you can't create directory at root level without special permissions.
