ImportError: No module named 'aiohttp.errors'

[fabianbaier]

Looks like in version 2.0.0 aiohttp dropped aiohttp.errors: https://media.readthedocs.org/pdf/aiohttp/2.0.0/aiohttp.pdf

When I try to load the library I get:

File "/Users/fabianbaier/anaconda/envs/libmaas/lib/python3.5/site-packages/maas/client/bones/__init__.py", line 19, in <module>
    import aiohttp.errors
ImportError: No module named 'aiohttp.errors'

pip freeze shows aiohttp==2.0.0 - as a work around I installed aiohttp==1.3.3 which produced no import error.

#96 pins aiohttp to >=2.0.0 and fixes the incompatibilities, so hopefully things will be up and running again in a bit. At some point we will freeze the dependencies... looks like sooner might be better than later.

mhhh still showing:

File "/usr/local/lib/python3.5/dist-packages/maas/client/viscera/__init__.py", line 39, in <module>
    from .. import bones
  File "/usr/local/lib/python3.5/dist-packages/maas/client/bones/__init__.py", line 20, in <module>
    import aiohttp.errors
ImportError: No module named 'aiohttp.errors'

@fabianbaier Can you try running python3.5 then:

>> import aiohttp
>> aiohttp.__version__

See what it says

[brendan-donegan]

@allenap I think @fabianbaier is on to something here. I just installed in a venv and it gave me aiohttp 2.0.1, but I still see the same error

[fabianbaier]

I patched it by installing aiohttp==1.3.3 as described above but even with that version:

root@86f797502acb:/# python3
Python 3.5.2 (default, Nov 17 2016, 17:05:23) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import aiohttp
>>> aiohttp.version
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'aiohttp' has no attribute 'version'

root@86f797502acb:/# pip3 freeze
aiohttp==1.3.3

@fabianbaier I think this fix hasn't been released yet. You could install from Github directly?

[brendan-donegan]

@allenap I think we should make a point of updating the setup.py file immediately after releasing so that it's clear that that version hasn't been released yet - I was a bit confused here because the version in the setup.py is 0.4.1 and that is what is in PyPi, but it's not the same code

[brendan-donegan]

@fabianbaier pip install git+https://github.com/maas/python-libmaas.git, fyi

[fabianbaier]

Yep, thanks that is working.

Interestingly it fixed also another issue I ran into:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'coroutine' object is not iterable

I was wondering why the TypeError was showing in the Docker container but not on my laptop when I am running it on my virtual env. So I checked the virtual env and the versions were everywhere identically. What made the difference and after upgrading back to aiohttp-2.0.1 I directly installed libmaas from Github and the error message disappeared:

I have aiohttp version 2.3.1 but still getting error

from aiohttp import errors
ImportError: cannot import name 'errors'

Is there any alternative to fix this issue?
