Ok, probing further trying to understand this. It looks like the job runner is 
trying to call set_meta() from galaxy_ext/metadata/set_metadata.py.  In there 
there’s a line that tries to set up the PATH:

# insert *this* galaxy before all others on sys.path
sys.path.insert( 1, os.path.abspath( os.path.join( os.path.dirname( __file__ ), 
os.pardir, os.pardir ) ) )

In my case the result is:

['/export/galaxy-central/database/job_working_directory/000/3’, 
'/galaxy-central/lib’, 
'/galaxy-central/lib’,
 
'/export/galaxy-central/database/job_working_directory/000/3/conda-env/lib/python27.zip’,
 
'/export/galaxy-central/database/job_working_directory/000/3/conda-env/lib/python2.7’,
 
'/export/galaxy-central/database/job_working_directory/000/3/conda-env/lib/python2.7/plat-linux2’,
 
'/export/galaxy-central/database/job_working_directory/000/3/conda-env/lib/python2.7/lib-tk’,
 
'/export/galaxy-central/database/job_working_directory/000/3/conda-env/lib/python2.7/lib-old’,
 
'/export/galaxy-central/database/job_working_directory/000/3/conda-env/lib/python2.7/lib-dynload’,
 
'/export/galaxy-central/database/job_working_directory/000/3/conda-env/lib/python2.7/site-packages’,
 
'/export/galaxy-central/database/job_working_directory/000/3/conda-env/lib/python2.7/site-packages/setuptools-25.1.6-py2.7.egg’
]

Looking for sqlalchemy, I find it installed at:

/galaxy-central/.venv/lib/python2.7/site-packages/sqlalchemy

so clearly that line of code is not doing what it should. I’m guessing that the 
Conda resolver is running the script within a conda env and the BETA magic 
hasn’t quite made it to the right place yet… 

BTW I was trying to understand the flags you mentioned but I can’t find 
GALAXY_CONFIG_ENABLE_BETA_TOOL_COMMAND_ISOLATION anywhere other than in sample 
Dockerfiles - is this some kind of magic incantation that creates a rift in 
space-time…enquiring minds want to know!!!
