covers #38

Hi @ohmrefresh,

if this is fine with you, could you merge this pull request, set a new tag and release and perform delivery of robotframework-jsonlibrary v0.4.0 to Pypi? It looks like you use Travis and I am unfamiliar with this API.

@elrandira i found some error on travis https://app.travis-ci.com/github/robotframework-thailand/robotframework-jsonlibrary/builds/250988675

thanks, i'll try to solve this.

quick analysis, it seems the issue is unrelated to this package but setup-tools would be the culprit. It is failling during pip install -r requirements.txt. Other package publishers had the same issue:

• [BUG] AttributeError: 'str' object has no attribute 'name' with setuptools 60.9.1+ pypa/setuptools#3293
• [BUG] vendored importlib.metadata of setuptools 60.9.0 fails with 'PathDistribution' object has no attribute '_normalized_name' pypa/setuptools#3102

and travis was switched from python 2.7 to 3.7 while solving issue #10.

I will try to get a Travis on my own repo. I need to understand what's going on
