OrderedDict错误，无法导入Funnelweb

Question

我正在尝试从一个网站导入一些静态页面使用plone的funnelweb附加组件。下面是我写的：bin/funnelweb --crawler:url=http://wiki.scandiatransplant.com --crawler:max=50 --ploneupload=http://admin:admin@localhost:8080/TestPage。

我得到了这个错误：

ImportError: cannot import name OrderedDict

下面添加了完整的回溯。有人知道怎么解决这个问题吗？

    ImportError: cannot import name OrderedDict

Answer 1

OrderedDict是Python2.7中添加的一个新类，因此在您的示例中缺少它。

您可以安装backport

pip install ordereddict

或者将其作为依赖项添加到构建中，然后编辑Plone/buildout-cache/eggs/transmogrify.webcrawler-1.2.1-py2.6.egg/transmogrify/webcrawler/webcrawler.py第21行以更改导入：

from collections import OrderedDict

至

try:
    from collections import OrderedDict
except ImportError:
    # python 2.6 or earlier, use backport
    from ordereddict import OrderedDict

我已经在funnelweb issue tracker中提交了一个问题，请求将其添加到该包的未来版本中，请参阅issue 22。
