I've created a bug report on Trello for reference: https://trello.com/c/o0S3klAF Traceback (most recent call last): File "./scripts/paster.py", line 33, in <module> serve.run() File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/util/pastescript/serve.py", line 1056, in run invoke(command, command_name, options, args[1:]) File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/util/pastescript/serve.py", line 1062, in invoke exit_code = runner.run(args) File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/util/pastescript/serve.py", line 227, in run result = self.command() File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/util/pastescript/serve.py", line 650, in command app = loadapp( app_spec, name=app_name, relative_to=base, global_conf=vars) File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/util/pastescript/loadwsgi.py", line 350, in loadapp return loadobj(APP, uri, name=name, **kw) File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/util/pastescript/loadwsgi.py", line 375, in loadobj return context.create() File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/util/pastescript/loadwsgi.py", line 813, in create return self.object_type.invoke(self) File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/util/pastescript/loadwsgi.py", line 249, in invoke return fix_call(context.object, context.global_conf, **context.local_conf) File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/util/pastescript/loadwsgi.py", line 97, in fix_call val = callable(*args, **kw) File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/webapps/reports/buildapp.py", line 61, in app_factory add_ui_controllers( webapp, app ) File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/webapps/reports/buildapp.py", line 33, in add_ui_controllers from galaxy.web.base.controller import BaseUIController File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/web/base/controller.py", line 23, in <module> from galaxy.visualization.genome.visual_analytics import get_tool_def File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/visualization/genome/visual_analytics.py", line 3, in <module> from galaxy.tools.parameters.basic import IntegerToolParameter, FloatToolParameter, SelectToolParameter File "/Users/lparsons/Documents/projects/sequencing/galaxy/galaxy-test1/lib/galaxy/tools/__init__.py", line 57, in <module> from galaxy.visualization.genome.visual_analytics import TracksterConfig ImportError: cannot import name TracksterConfig Removing PID file reports_webapp.pid -- Lance Parsons - Scientific Programmer 134 Carl C.
