使用PyBOMBS安装GNU Radio

Question

我正在按照https://github.com/gnuradio/pybombs上的安装说明进行操作。

我得到以下错误消息：

→ sudo -H pybombs prefix init ~/prefix -a myprefix -R gnuradio-default
PyBOMBS.ConfigManager - INFO - Prefix Python version is: 2.7.6
PyBOMBS - INFO - PyBOMBS Version 2.3.3a0

Package <ruamel.yaml.comments.CommentedSeq object at 0x7f3891d44d20> has no recipe file!

这似乎与ruamel.yamel的使用不匹配。重新安装ruamel.yamel并不能解决这个问题：

→ sudo -H pip install --upgrade --force-reinstall ruamel.yaml

我使用的是Ubuntu 14.04.4 LTS (由于各种原因，我无法升级)。

我们将非常感谢您的任何建议。

Answer 1

PyBOMBS无法应对ruamel.yaml中最近的变化，CommentedMap和CommentedSeq不再是dict resp list的子类，而是MutableMapping抽象基类的子类。MutableSequence (来自collections.abc)。PyBombs实际上使用isinstance()对dict进行了检查。list。

安装旧版本的ruamel.yaml (anything <= 0.15.52)应该可以，您可以使用pip install 'ruamel.yaml<=0.15.52'进行安装

同时提交了一个PR并合并来解决这个问题，所以请确保您运行的是从github签出的最新版本的PyBOMBS。

您的config.yml可能已被截断，因此请确保恢复/重新生成该sure。
