按照教程自动安装RFNoC时.在使用pip安装pybombs时出现报错,解决办法

1  $ sudo apt-get install git
2  $ sudo apt-get install python-setuptools python-dev python-pip build-essential 
3  $ sudo pip install git+https://github.com/gnuradio/pybombs.git

　　安装到第三步时出现报错:

No matching distribution found for ruamel.yaml>=0.15.0 (from PyBOMBS===2.3.4a0)

解决办法:

1 sudo apt-get purge runit
2 sudo apt-get purge git-all
3 sudo apt-get purge git
4 sudo apt-get autoremove
5 sudo apt update

　　重新运行第3句:
