python - 无法安装触发网络自动化工具

Question

我在 howto 文档中阅读了 install Trigger , 但是当我在 python 环境中测试时，我得到以下错误:

>>> from trigger.netdevices import NetDevices
>>> nd = NetDevices()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/trigger/netdevices/__init__.py", line 913, in __init__
    with_acls=with_acls)
  File "/usr/local/lib/python2.7/dist-packages/trigger/netdevices/__init__.py", line 767, in __init__
    production_only=production_only, with_acls=with_acls)
  File "/usr/local/lib/python2.7/dist-packages/trigger/netdevices/__init__.py", line 83, in _populate
    #    device_data = _munge_source_data(data_source=data_source)
  File "/usr/local/lib/python2.7/dist-packages/trigger/netdevices/__init__.py", line 73, in _munge_source_data
    #    return loader.load_metadata(path, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/trigger/netdevices/loader.py", line 163, in load_metadata
    raise RuntimeError('No data loaders succeeded. Tried: %r' % tried)
RuntimeError: No data loaders succeeded. Tried: [<trigger.netdevices.loaders.filesystem.XMLLoader object at 0x7f550a1ed350>, <trigger.netdevices.loaders.filesystem.JSONLoader object at 0x7f550a1ed210>, <trigger.netdevices.loaders.filesystem.SQLiteLoader object at 0x7f550a1ed250>, <trigger.netdevices.loaders.filesystem.CSVLoader object at 0x7f550a1ed290>, <trigger.netdevices.loaders.filesystem.RancidLoader object at 0x7f550a1ed550>]

有没有人知道如何修复它？

Answer 1

NetDevices 构造函数显然试图找到不存在的“元数据源”。

首先，您需要define the metadata .其次，您的代码应该处理未发现的异常。
