我正在按照 https://github.com/gnuradio/pybombs 上的安装说明进行操作。
我收到以下错误消息：

这似乎是使用ruamel.yamel的不匹配。重新安装 ruamel.yamel 并不能解决这个问题：

任何建议将不胜感激。
PyBOMBS 无法应对 ruamel.yaml 的最新变化，其中CommentedMap和CommentedSeq不再是dictresplist的子类，而是抽象基类MutableMappingresp 的子类。MutableSequence(从collections.abc开始(。PyBombs实际上使用isinstance()检查了dict。list.
安装旧版本的ruamel.yaml(任何<= 0.15.52(应该可以工作，您可以使用pip install 'ruamel.yaml<=0.15.52'
同时提交 PR 并合并以解决此问题，因此请确保您使用从 github 签出的最新版本的 PyBOMBS 运行。
您的config.yml很可能被截断了，因此请确保还原/重新生成该。
