Ah should have seen it in the path. I'm having trouble reproducing it though...

Any ideas?

Ah, just noticed you meant the error happens on import, not install. Checking.

from urllib3.

Hmm, seems to work during import too:

<module 'urllib3.exceptions' from '/Users/shazow/env/urllib3/lib/python2.7/site-packages/urllib3-1.3-py2.7.egg/urllib3/exceptions.pyc'>
>>>

from urllib3.

oh i know, i check this
it's just because i used eventlet.import_patched
urllib3 = eventlet.import_patched('urllib3')
from urllib3 import HTTPSConnectionPool

but with version 1.2.2 this will be fine

from urllib3.

Ah, that is indeed a problem. Any interest in fixing it? :)

I was hoping to have exceptions available under urllib3.exceptions without an extra import if possible.

from urllib3.

ok i'll try to do this

from urllib3 import exceptions
Traceback (most recent call last):

after viewing the source code of eventlet
i think this is just a eventlet.import_patched bug(as shown above)
but i still dont know exactly where is the bug in eventlet
i'll check it again later

if you have times, you can check this
https://bitbucket.org/which_linden/eventlet/src/a60be8a9cdb5/eventlet/patcher.py

if you find what causes this,
please let me know
thanks in advance

after import urllib3
some attributes were lost

from urllib3.

Hmm, here's the set difference:

['_collections',
 'request',
 'connectionpool',
 'filepost',
 'poolmanager',
 'exceptions',
 'packages',
 'response']

from urllib3.

it's not necessary to use eventlet.import_patched('urllib3')(but the bug is existed exactly)
eventlet.patcher.monkey_patch() can patch all the modules that eventlet can provide
so
eventlet.patcher.monkey_patch()
import urllib3
it will work for me
