socket.herror: [Errno 1] Unknown host
It is same code 2 different Centos versions. First one is 6.5, custom python installation of 2.7.6. Second one is Centos 7 and 2.7.5 default installation. When i manually check both servers can find this host with whois cli tool.
I got stuck and I could not find what is the difference between both machines. They are based on same Network subnet, using same network config except IP addresses.
Does this a difference between versions ? Does anybody has an idea about this ?

there might be an issue with the path or the permission of the required libraries. But i am not sure how to fix this.
I am executing my script from Jenkins and it throws error over there. Please guide how to fix.
I installed Twilio:
pip3 install twilio
But it will run only from the Python 3 Applications folder.

Anyone know why it works in the Python 3.7 directory and gives an error anywhere else? How do I fix this?

I'm getting this error by operating on a dictionary resulting from a Twitter Json array (Twython module) however I don't think the fault is there.
A little inspection shows this is happening with foreign languages.
The Question:
How do I deal with this inconsistency between environments?
The default encoding in your 'Server' environment is not the same as the Ubuntu environment. Try u['name'].encode('utf-8')

Instead of using poll, use select.kqueue() on OSX. It's similar to 'epoll' on Linux in that you can more efficiently register for types of file-descriptor / file system events which can be used in asynchronous code. Much more efficient than polling.
Otherwise, the equivalent is just running a blocking select.select() inside a while True: loop with some sort of timeout?
If you want to use poll in order to not rewrite a bunch of code for kqueue, it is built in to the python compiled from macports (macports.org). You just must specify that python instance explicitly (/opt/local/bin/python2.7 in my case) because OSX's python (/usr/bin/python) will by default be earlier in the search path.
Interestingly for future reference, this only comes up with a limited subset of the versions of python
