Installation Problem with pip

[npmontgomery]

I get the following message when I try to install with pip. Any ideas for troubleshooting?

bash-3.2$ pip install cogdb
Collecting cogdb
Could not find a version that satisfies the requirement cogdb (from versions: )
No matching distribution found for cogdb

[arun1729]

@npmontgomery what version of python are you running?

[arun1729]

could you please run pip install -vvv cogdb and paste the output here?

[npmontgomery]

@arun1729 As you'll see in the output below, I've included the output from Python 3.7 and 3.6 (below)
Thank you for your help!

the current version of cog only runs on python >= 2.7. It may work on slightly older version but not tested for that. Python 3 is currently not supported, but this will be addressed in the near future. Are you be able to use python 2.x?

[npmontgomery]

I can try on 2.7. Thank you for helping with this!
Friendly suggestion: Perhaps adding the Python version support information to the page would help others from encountering the same problem.

[arun1729]

thanks for the suggestion! I have added python 2.7 badge to the project.
