无法运行pebble javascript模拟器(pypkjs)

Question

我正在尝试设置PebbleKit JS模拟器，以便能够在没有Pebble-Watch本身的情况下完全开发。我按照他们的github repo上的指示安装了模拟器，但是当我按照他们的github上的指示运行模拟器时，我收到了错误，我找不到原因。我重新安装了几次，错误仍然存在。(我已经安装了QEMU-Emulator，它工作正常)

似乎JS-Simulator无法连接到QEMU-Emulator。下面是我在运行./phonesim.py时没有打开QEMU时的终端输出：

Namespace(debug=False, layout=None, oauth=None, pbws=[], persist=None, port=9000, qemu='127.0.0.1:12344', ssl_root=None, token=None)
['127.0.0.1', '12344']
INFO:pypkjs:Ready. Loaded apps:
Traceback (most recent call last):
  File "./phonesim.py", line 31, in <module>
    runner.run()
  File "/Users/manuelburger/pypkjs/runner/websocket.py", line 56, in run
    pebble_greenlet = self.pebble.connect()
  File "/Users/manuelburger/pypkjs/pebble_manager.py", line 29, in connect
    self.pebble.connect()

    raise ConnectionError(str(e))
libpebble2.exceptions.ConnectionError: [Errno 61] Connection refused

这是运行./jskit.py localhost:12344 watchface1.pbw时的输出，其中QEMU运行watchface1.pbw：

['localhost', '12344']

  File "./jskit.py", line 28, in <module>

  File "/Users/manuelburger/pypkjs/timeline/model.py", line 312, in prepare_db
    db.connect()

    self.__local.closed = False

  File "/Library/Python/2.7/site-packages/peewee.py", line 3016, in _connect
    conn = sqlite3.connect(database, **kwargs)
peewee.OperationalError: unable to open database file

对于解决这个问题的任何帮助和建议，我们都非常感谢。

我发现了几件事：

1. 我的默认端口不是12344。在运行时运行'ps -ax | grep qemu‘，您可以看到正在使用哪个端口。我的是通过'localhost:41968‘连接的。可能有一种更好的方法来获取qemu的实际端口，但这是可行的。对于phonesim.py，您需要指定到qemu的连接和端口，您也可以从上面的ps命令的输出中复制该端口。例如，在我的例子中，它失败了，除非我运行它为'./phonesim.py --qemu localhost:41968'
2. jskit尝试打开数据库'data/timeline.db‘失败，所以你需要在你运行jskit的文件夹中创建一个名为'data’的子目录。如果jskit为你创建了这个文件夹就好了，但它似乎不是。

希望这能有所帮助！
