Hi all! Back again with a second attempt, this time I'm not trying to modify the host system so I'm hoping this should be a lot easier/possible!
Here's my snapcraft.yaml: https://git.launchpad.net/~robru/+git/weightloss/tree/snapcraft.yaml Pretty simple little flask webapp, just does some data manipulations and then serves graphics over HTTP. Snap builds ok but when I run it I get this: weighttracker Traceback (most recent call last): File "/snap/weighttracker/x2/run.py", line 15, in <module> from graph import draw File "/snap/weighttracker/x2/graph.py", line 14, in <module> from matplotlib.dates import DateFormatter File "/snap/weighttracker/x2/usr/lib/python3/dist-packages/matplotlib/__init__.py", line 1133, in <module> rcParams = rc_params() File "/snap/weighttracker/x2/usr/lib/python3/dist-packages/matplotlib/__init__.py", line 977, in rc_params return rc_params_from_file(fname, fail_on_error) File "/snap/weighttracker/x2/usr/lib/python3/dist-packages/matplotlib/__init__.py", line 1102, in rc_params_from_file config_from_file = _rc_params_in_file(fname, fail_on_error) File "/snap/weighttracker/x2/usr/lib/python3/dist-packages/matplotlib/__init__.py", line 1020, in _rc_params_in_file with _open_file_or_url(fname) as fd: File "/snap/weighttracker/x2/usr/lib/python3.5/contextlib.py", line 59, in __enter__ return next(self.gen) File "/snap/weighttracker/x2/usr/lib/python3/dist-packages/matplotlib/__init__.py", line 1005, in _open_file_or_url with io.open(fname, encoding=encoding) as f: PermissionError: [Errno 13] Permission denied: '/etc/matplotlibrc' Not really sure what's going on, but it looks like matplotlib is hard-coding "/etc": $ cat /snap/weighttracker/x2/usr/lib/python3/dist-packages/matplotlib/__init__.py | grep /etc path = '/etc' # guaranteed to exist or raise Do I have to patch matplotlib here or is there some way snapcraft can fix this for me? (frustratingly the matplotlib code seems to harmlessly ignore the file if it doesn't exist, but they didn't anticipate the idea that they wouldn't have permission, so the code just barfs) Thanks. -- robru -- Snapcraft mailing list Snapcraft@lists.snapcraft.io Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/snapcraft
