    while cls._get_process_states(worker_state):
                                  ^^^^^^^^^^^^
UnboundLocalError: cannot access local variable 'worker_state' where it is not associated with a value

Code snippet

app = Sanic("fuwu")

from sanic import Sanic, text, json

app = Sanic("fuwu")

if __name__ == '__main__':
    app.run(host="0.0.0.0", port=8000)

Setting the correct host name seems to address the issue. But we might want to implement a host name validator to avoid confusing error message.

把host里的,改为.即可解决问题。同时建议在Linux或Unix系统上尝试

This is still a bug, however. mixins.startup.serve should still exit gracefully—fixed in my PR.
