Instructions for importing data are not working

[AcckiyGerman]

I cannot use data from the datahub following the instruction

How to reproduce

Go to any dataset page on the datahub.io and try to use the dataset due to instructions, e.g. http://datahub.io/core/cofog#python

expected behavior

• [x] I copy the example in my REPL
• [x] It works
  • [x] R
  • [x] Pandas
  • [x] Python
  • [x] JavaScript
  • [ ] Ruby

@Mikanebu is it now ready for testing ?

[Mikanebu]

@AcckiyGerman created PR. It is under review. I will ping you

TESTED: Python: OK Pandas: OK nodejs: FAIL

Promise {

  domain: 
   Domain {
     domain: null,
     _events: { error: [Function: debugDomainError] },
     _eventsCount: 1,
     _maxListeners: undefined,
     members: [] } }

R: FAIL OK

Ruby: Works but not with all the datasets. We agree (the team) to replace Ruby with Bash script (using Curl)
