如何解决 rethinkdb 连接被拒绝的问题？

Question

我在https://github.com/flaree/Flare-Cogs/tree/master/dankmemer 关注本指南。我进入了 import rethinkdb 部分，但是在运行 r.connect('localhost', 28015).repl() 时出现此错误 命令。昨天一直在寻找修复方法，但找不到。

r.connect('localhost', 28015).repl()
Traceback (most recent call last):
  File "/root/venv/lib/python3.8/site-packages/rethinkdb/net.py", line 349, in __init__
    self._socket = socket.create_connection((self.host, self.port), timeout)
  File "/usr/lib/python3.8/socket.py", line 808, in create_connection
    raise err
  File "/usr/lib/python3.8/socket.py", line 796, in create_connection
    sock.connect(sa)
ConnectionRefusedError: [Errno 111] Connection refused

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/root/venv/lib/python3.8/site-packages/rethinkdb/__init__.py", line 93, in connect
    return self.make_connection(self.connection_type, *args, **kwargs)
  File "/root/venv/lib/python3.8/site-packages/rethinkdb/net.py", line 830, in make_connection
    return conn.reconnect(timeout=timeout)
  File "/root/venv/lib/python3.8/site-packages/rethinkdb/net.py", line 696, in reconnect
    return self._instance.connect(timeout)

    self._socket = SocketWrapper(self, timeout)

    raise ReqlDriverError(

您需要先运行 rethinkdb。 输入您的 venv，然后运行 ​​tmux。然后在你的 tmux shell 中运行rethinkdb。这将启动 rethinkdb 服务器，并使其保持运行。关闭 SSH 会话，然后打开另一个会话。再次尝试运行您的代码。
