Strange circleCI error with requirements.txt file

[angrygoats]

I'm using your library on a personal project of mine I have running with circleCI. I've been getting the following build stopper recently -

Collecting oandapy==0.1 (from -r requirements.txt (line 12))
  Could not find a version that satisfies the requirement oandapy==0.1 (from -r requirements.txt (line 12)) (from versions: )
No matching distribution found for oandapy==0.1 (from -r requirements.txt (line 12))

pip install -r requirements.txt returned exit code 1

To fix this - you need this line in your requirements.txt

-e git+https://github.com/oanda/oandapy.git#egg=oandapy

I hope this helps someone else.
