ImportError：没有名为oslo_config.cfg的模块 - Ryu App

Question

我正在运行一个样本Ryu应用程序，如下所示：https://ryu-zhdoc.readthedocs.org/en/latest/writing_ryu_app.html

但是我收到以下错误：

     Traceback (most recent call last):
  File "/usr/local/bin/ryu-manager", line 9, in <module>
    load_entry_point('ryu==3.29.1', 'console_scripts', 'ryu-manager')()
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 351, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2363, in load_entry_point
    return ep.load()
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2088, in load
    entry = __import__(self.module_name, globals(),globals(), ['__name__'])
  File "/usr/local/lib/python2.7/dist-packages/ryu/cmd/manager.py", line 31, in <module>
    from ryu import cfg
  File "/usr/local/lib/python2.7/dist-packages/ryu/cfg.py", line 17, in <module>
    import oslo_config.cfg
ImportError: No module named oslo_config.cfg

我已经尝试过以下命令，但尚未解决我的问题：

sudo pip install oslo.config
sudo apt-get upgrade python-oslo.config
sudo apt-get install python-oslo python-netaddr

我刚刚开始熟悉Ryu，并感谢任何解决此问题的方法。谢谢！

Answer 1

您正在python 2.7中运行您的应用程序。

请确保您没有任何旧版本的python附带Linux发行版。请阅读我的另一篇文章，看看它是否有帮助。 qazxsw poi

Answer 2

如果你想轻松安装ryu应用程序，请尝试no module named numpy python2.7。这对我有用。

Answer 3

Try this, It worked like wonder for me:

pip install'oslo.config <2.0.0'
