After install and all 349 test passed, the first actual curl request just hangs forever?

[seeotter1]

I just did a fresh install, just as the install directions specify, and it seems that all the tests ran ok. But when I do an actual curl, after all the tests run, it just hangs with no return, here a partial transcript. Nothing happens after that last line (the request)

Can you try invoking curl with --verbose and see what it spits out?

I can't reproduce.

First, I started the example application, then, in a new terminal window:

❯ curl -XPOST http://localhost:8000/parse --data 'locale=en_GB&text=tomorrow at eight' | jq
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

        },
        {

      ],

Any updates, @LiNengRan?

I think you CURLed in the same terminal while duckling was running, which definitely won't work since duckling 1) doesn't listen to stdin 2) isn't a terminal.

If I am wrong and the issue persists for you (when curling in a separate terminal) feel free to re-open and let me know.
