我在使用 Python 3.9.9 和 jsonpickle 2.0.0 将 JSON 解码为字典时遇到问题。
JSON 如下所示：

它是用这个命令编码的jsonpickle.encode(data, keys=True)，其中dataa 是dict(). 在 Windows 机器上解码 JSON 工作，相同的 Python，相同的 jsonpickle 包。在 Raspbian 上，它不适用于相同的版本。
错误jsonpickle.decode如下（但是，其他 JSON 数据可以使用相同的环境进行解码，并且可以毫无问题地调用，但那些字典并不那么复杂）：
m = jsonpickle.decode(msg.payload, keys=True)

不幸的是，我不知道在哪里发布此类问题（jsonpickle），这就是我在这里试试运气的原因。在 GitHub 上，只有报告错误的可能性。
