Currently, the app-emulation/docker-compose-1.21.2 package currently depends on (ebuild) docker-py-3.2.1. When installing and executing docker-compose with this version, however, the application crashes with the attached backtrace, telling that docker-compose needs at least version 3.3.0 of docker lib.
Created attachment 537380 [details] Backtrace
In summary: I confirm this, installing dev-python/docker-py-3.3.0 resolves the issue. But it must be version 3.3. Portage also has dev-python/docker-py-3.4.0 available, but that doesn't work either because v3.4 needs docker-pycreds>=0.3.0 and the highest version we available on portage right now is dev-python/docker-pycreds-0.2.3. Complete reproduction: After upgrade from app-emulation/docker-compose-1.21.0 (not available on portage anymore) to app-emulation/docker-compose-1.21.2, docker-compose is broken and fails with the following message: $ docker-compose --help Traceback (most recent call last): File "/usr/lib/python-exec/python2.7/docker-compose", line 6, in <module> from pkg_resources import load_entry_point File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 3161, in <module> @_call_aside File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 3145, in _call_aside f(*args, **kwargs) File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 3174, in _initialize_master_working_set working_set = WorkingSet._build_master() File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 668, in _build_master return cls._build_from_requirements(__requires__) File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 681, in _build_from_requirements dists = ws.resolve(reqs, Environment()) File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 870, in resolve raise DistributionNotFound(req, requirers) pkg_resources.DistributionNotFound: The 'docker<4.0,>=3.3.0' distribution was not found and is required by docker-compose After upgrade from dev-python/docker-py-3.2.1 to dev-python/docker-py-3.4.0, the docker-compose is still broken, complaining about docker-pycreds, it fails with the following message: $ docker-compose --help Traceback (most recent call last): File "/usr/lib/python-exec/python2.7/docker-compose", line 6, in <module> from pkg_resources import load_entry_point File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 3161, in <module> @_call_aside File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 3145, in _call_aside f(*args, **kwargs) File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 3174, in _initialize_master_working_set working_set = WorkingSet._build_master() File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 668, in _build_master return cls._build_from_requirements(__requires__) File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 681, in _build_from_requirements dists = ws.resolve(reqs, Environment()) File "/usr/lib64/python2.7/site-packages/pkg_resources/__init__.py", line 870, in resolve raise DistributionNotFound(req, requirers) pkg_resources.DistributionNotFound: The 'docker-pycreds>=0.3.0' distribution was not found and is required by docker It says it requires docker-pycreds>=0.3.0, but that version is not available on portage yet. So I downgraded docker-py to version 3.3.0 and everything is working fine now.
Fixed in -r1
