I have installed poezio, when executing it (with Python 3.6) the following error occurs: % poezio Traceback (most recent call last): File "/usr/lib/python-exec/python3.6/poezio", line 6, in <module> from pkg_resources import load_entry_point File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3126, in <module> @_call_aside File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3110, in _call_aside f(*args, **kwargs) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3139, in _initialize_master_working_set working_set = WorkingSet._build_master() File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 581, in _build_master ws.require(__requires__) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 898, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 784, in resolve raise DistributionNotFound(req, requirers) pkg_resources.DistributionNotFound: The 'typing' distribution was not found and is required by aiodns dev-python/typing-extensions is installed with python_targets_python3_6.
Hi gerion, is this poezio 9999 or 0.12?
poezio-0.12
Sorry, could you please double check that you surely are using Python 3.6? "Typing" should just be there in 3.6. I read in Poezio changelog that 0.12 had an issue under Python 3.5.
Thanks that you try to solve the problem. I have double checked. Below is some log output that shows that this is definitely Python 3.6: ``` % poezio Traceback (most recent call last): File "/usr/lib/python-exec/python3.6/poezio", line 6, in <module> from pkg_resources import load_entry_point File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3126, in <module> @_call_aside File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3110, in _call_aside f(*args, **kwargs) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3139, in _initialize_master_working_set working_set = WorkingSet._build_master() File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 581, in _build_master ws.require(__requires__) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 898, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 784, in resolve raise DistributionNotFound(req, requirers) pkg_resources.DistributionNotFound: The 'typing' distribution was not found and is required by aiodns % python Python 3.6.5 (default, May 16 2018, 11:13:27) [GCC 6.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> exit() % python3.6 /usr/lib/python-exec/python3.6/poezio Traceback (most recent call last): File "/usr/lib/python-exec/python3.6/poezio", line 6, in <module> from pkg_resources import load_entry_point File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3126, in <module> @_call_aside File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3110, in _call_aside f(*args, **kwargs) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3139, in _initialize_master_working_set working_set = WorkingSet._build_master() File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 581, in _build_master ws.require(__requires__) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 898, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 784, in resolve raise DistributionNotFound(req, requirers) pkg_resources.DistributionNotFound: The 'typing' distribution was not found and is required by aiodns % eselect python list Available Python interpreters, in order of preference: [1] python3.6 [2] python2.7 (fallback) ``` A strange thing is that I can import typing and aiodns without problems from Python directly. ``` % python3.6 Python 3.6.5 (default, May 16 2018, 11:13:27) [GCC 6.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import aiodns >>> import typing >>> exit() ``` I can make some debugging if you have an idea where this behavior comes from. I'm not really sure how the python-exec wrapper works and how to reproduce the error directly (without python-exec). In the Python console the error is reproducible (with python-exec): ``` % python Python 3.6.5 (default, May 16 2018, 11:13:27) [GCC 6.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> __requires__ = 'poezio==0.12' >>> from pkg_resources import load_entry_point Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3126, in <module> @_call_aside File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3110, in _call_aside f(*args, **kwargs) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 3139, in _initialize_master_working_set working_set = WorkingSet._build_master() File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 581, in _build_master ws.require(__requires__) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 898, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/lib64/python3.6/site-packages/pkg_resources/__init__.py", line 784, in resolve raise DistributionNotFound(req, requirers) pkg_resources.DistributionNotFound: The 'typing' distribution was not found and is required by aiodns ```
Ok, after some debugging, this seems to be a problem of aiodns packaging aiodns installs an egg-info/requires.txt with this content: ``` pycares>=3.0.0 [:python_version < "3.7"] typing ``` Therefore the pkg_resources seems to search a distribution (aka third party package) of typing for Python3.6. Since typing is build-in there, the distribution is not found. I have no idea, however, how the requires egg-info is created, so why the 3.7 is mentioned there.
Ok, this results from the upstream setup.py: https://github.com/saghul/aiodns/blob/master/setup.py#L22
