Fails: Environment object has no attribute get_db_ctx

[Quince]

Trying to migrate in-place from MySQL to PostgreSQL. Prepared user and empty database in PostgreSQL and ran ./trac-migrate.py --in-place /srv/trac postgres://tracuser:xxxxxxxx@127.0.0.1/trac?schema=new_schema Result:

/usr/lib/python2.7/site-packages/pkg_resources.py:1054: UserWarning: /root/.python-eggs is writable by group/others and vulnerable to attack when used with get_resource_filename. Consider a more secure location (set with .set_extraction_path or the PYTHON_EGG_CACHE environment variable).

Any fix or work-around? Thanks

A duplicate of #11651. Also, it is a TracJsGanttPlugin isssue.

The plugin doesn't work if it's enabled on initenv.

$ cat inherit.ini
[components]
tracjsgantt.* = enabled

[logging]
log_type = stderr
log_level = DEBUG

$ ~/venv/trac/1.0.1/bin/trac-admin ~/var/trac/th11651 initenv --inherit=$PWD/inherit.ini th11651 sqlite:db/trac.db

It seems to be no work around.
