我正在尝试使用这个库，但是遇到了错误

Question

我安装了一个名为pymodeS的库来解码ADSB消息，但在运行modeslive命令时，根据自述文件，出现了一些错误消息，我无法解决它们

这是链接：https://github.com/junzis/pyModeS/blob/master/README.rst

# modeslive --help

我将安装命令从pip install pyModeS更改为pip3 install pyModeS，现在它显示了以下问题

enter code here
modeslive -h

我想你在mac里。您是否安装了librtlsdrbrew install librtlsdr
