NameError: uninitialized constant Net::HTTPCreated ?

Hello!

I am following this guide here
<http://predictionio.incubator.apache.org/demo/tapster/> and am getting
error pasted below.

rake aborted!

This happens when I try to post data to the predictionIO by executing "rake
import:predictionio".
I am not sure how to trace through the code with this.
Has anyone experienced this bug?

Best Regards,
Jenna Kwon

Dear Chan,

Putting that line on the top of my predictionio.rake file did the trick. I
am new to ruby so I am unsure why but thank you!

Best Regards,
Jenna Kwon

Re: NameError: uninitialized constant Net::HTTPCreated ?

Posted by Chan Lee <ch...@gmail.com>.

Hi Jenna,

I've never experienced this bug, but looking at the log, it seems that when
application calls the PredictionIO Ruby SDK, it fails to load Net::HTTP
module. The code responsible should be here: https://github.com/Predi
ctionIO/PredictionIO-Ruby-SDK/blob/develop/lib/predictionio/
event_client.rb#L327.

'require "net/http"' (L8) should suffice for Ruby v2.0 or higher, so I
don't know why this error occurs in your case. Are you using SSL by any
chance?

Cheers,
Chan
