Open browser with URL in Ruby - ruby

Question

I've been using the following to launch the default browser in OS X:
system('open', url)
This has been working fine until upgrading to Yosemite. Now, I frequently get this message when trying to open various URLS:
LSOpenURLsWithRole() failed with error -1712 for the URL http://blah.com
But sometimes that URL will work. I can try it once, and it'll work, another it might not. Very unpredictable.
I've tried all of these:
system("open #{url}")
`open #{url}`
Launchy.open(url, debug: true)
Launchy.open( "#{ url }" ) do |exception|
puts "Attempted to open #{url} and failed because #{exception}"
end
But they all exhibit this same behavior. There are several URLs being opened at once, like this:
urls.each do |url|
system("open #{url}")
end
How can I consistently open a specific URL in my browser on OS X using ruby?

Answer 1

It looks like you are pushing the Browser with too many urls at the same time.
Using sleep seems to work fine.
15.times {|i| `open http://google.com?q=#{i}` }
# LSOpenURLsWithRole() failed with error -1712 for the URL http://google.com?q=5.
# LSOpenURLsWithRole() failed with error -1712 for the URL http://google.com?q=6.
# LSOpenURLsWithRole() failed with error -1712 for the URL http://google.com?q=12.
# LSOpenURLsWithRole() failed with error -1712 for the URL http://google.com?q=14.
# => 15
15.times {|i| sleep(0.2); `open http://google.com?q=#{i}` }
# => 15
