python - 我正在尝试使用这个库 pyModeS，但遇到了错误

问题描述

我安装了一个名为pymodeS解码 ADSB 消息的库，但是在运行modeslive命令时，根据自述文件，弹出一些错误消息，我无法解决它们。

# modeslive --help

    func = self._FuncPtr((name_or_ordinal, self))

AttributeError: /usr/bin/python3: undefined symbol: rtlsdr_get_device_count

解决方案

我想你在mac中。你安装了librtlsdr吗？brew install librtlsdr
