engineio has conditional logic to load asyncio files when running under
Python 3.x:
if sys.version_info >= (3, 5): # pragma: no cover
from .asyncio_server import AsyncServer
from .asyncio_client import AsyncClient
from .async_drivers.asgi import ASGIApp
try:
from .async_drivers.tornado import get_tornado_handler
except ImportError:
get_tornado_handler = None
else: # pragma: no cover
AsyncServer = None
AsyncClient = None
get_tornado_handler = None
ASGIApp = None
pycompile unfortunately errors out on these files when running under Python
2.x:
../scripts/pycompile.py ..
error: File "/usr/lib/python2.7/site-packages/engineio/asyncio_socket.py", line 13
async def poll(self):
^
SyntaxError: invalid syntax
As a workaround, simply drop the unusable file from TARGET_DIR if building
for python 2.x.
