I am getting this warning when I try to install benoitc/gunicorn (branch fix/830) on python 2:

warning: no previously-included files matching '*.pyo' found under directory 'examples'
   File "/Users/benoitc/work/gunicorn_py2/lib/python2.7/site-packages/gunicorn/workers/gaiohttp.py", line 76
     yield from iterator
              ^
 SyntaxError: invalid syntax

While the python 3 support of this worker is handled by testing the version of python 3 in gunicorn, it seems that pip is trying to check the syntax of any modules depending on the version of Python it's running on. Is there any good way to remove this warning ?

More information about it. The error happen when it is trying to byte-compile the module:

 byte-compiling /Users/benoitc/work/gunicorn_py2/lib/python2.7/site-packages/gunicorn/workers/gaiohttp.py to gaiohttp.pyc
   File "/Users/benoitc/work/gunicorn_py2/lib/python2.7/site-packages/gunicorn/workers/gaiohttp.py", line 76
     yield from self.wsgi.close()
              ^
 SyntaxError: invalid syntax
