问题
I am trying to install cx_Oracle on my windows PC. I ran following command in command prompt:
pip install cx_Oracle
This is giving me the following error:
Collecting cx-Oracle
Could not find a version that satisfies the requirement cx-Oracle (from versions: )
No matching distribution found for cx-Oracle
I am using windows 64bit machine and Python 3.5(Anaconda3). Intsalled Oracle vcersion on my PC is Oracle 11.2.0.1.0 and oracle-instantclient version oracle-instantclient-11.2.0.4.0-0
Please let me know what am I missing. Should I downgrade my python version to 3.4? If yes, than how to do it using command line in Anaconda?

I got past this issue by following these steps:
Create a Python 3.4 environment
Windows + R to open Run
Type 'cmd' (no apostrophes) and hit enter to open the command prompt.
Type the following:
$ conda create -n py34 python=3.4 anaconda
Activate and update the new environment
$ activate py34
$ conda update conda
Uninstall and reinstall the qt aspect of Spyder
This step fixes a qt issue with Spyder when trying to open from your py34 environment
$ conda remove qt --name py34
$ conda install qt=4.8.7=vc10_4
To Test
Make sure you have your py34 environment activated.
$ spyder # will launch spyder
In the Interactive Console in Spyder type:
$ import cx_Oracle # the O in Oracle must be capitalized
If it doesn't error out, you're done!
