About numenta-apps supervisord.conf setting problem

According to the supervisord.conf in the taurus_engine of the numenta-apps , how can I set the parameters “ENV_TAURUS_RMQ_METRIC_DEST” and “ENV_TAURUS_RMQ_METRIC_PREFIX”
when I run the – supervisord -c conf-user/supervisord.conf , it always shows
error: Format string ‘python -m htmengine.monitors.rmq_metric_collector_agent --metric-addr=%(ENV_TAURUS_RMQ_METRIC_DEST)s --metric-prefix=TAURUS’ for ‘command’ contains names which cannot be expanded.
How can l solve the one? Thank you!
