Can't run dev branch

Since a moment, I can't run Sakia excepted on dev0114 branch,

on dev branch, I get:

  File "src/sakia/main.py", line 19, in <module>
    from quamash import QSelectorEventLoop
ImportError: cannot import name 'QSelectorEventLoop'

I fixed it when you changed ucoin-python-api and I could fixed it installing requirement.txt.

I tried to reinstalled requirements, with last pip:

(env-sakia) [moul@moulinette build]$ sudo pip install requirements.txt
Mot de passe [sudo] de moul :
Collecting requirements.txt
  Could not find a version that satisfies the requirement requirements.txt (from versions: )
No matching distribution found for requirements.txt

Where am I missing something?
