漏斗网错误，无法导入有序字典。

Question

我正在尝试使用Plone的FunnelWeb插件导入网站的一些静态页面。这是我写的命令：bin/funnelweb --crawler:url=http://wiki.scandiatransplant.com --crawler:max=50 --ploneupload=http://admin:admin@localhost:8080/TestPage。

但是我收到了以下错误：

ImportError: cannot import name OrderedDict

完整的回溯信息如下。有人知道如何解决吗？

Answer 1

OrderedDict是Python 2.7新增的一个类，所以在您的情况下缺少它。

您可以安装一个后端支持:

pip install ordereddict

或者在你的buildout中将其添加为依赖项，并编辑Plone/buildout-cache/eggs/transmogrify.webcrawler-1.2.1-py2.6.egg/transmogrify/webcrawler/webcrawler.py第21行，更改导入方式为：

from collections import OrderedDict

到

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

我已在 funnelweb问题跟踪器 中提交了一个问题，请求将此添加到未来版本的软件包中，请参见issue 22。

导入orderreddict在Python提示符中运行正常，但导入OrderededDict失败。这样可以吗？ - user1960836

@user1960836：是的，当然可以。你需要从模块中导入：from ordereddict import OrderedDict。 - Martijn Pieters

这不太易读。有没有办法我可以将其作为注释使其更易读？顺便说一下，那是：head bin/funnelweb - user1960836

好的，我注意到它正在使用Python 2.6。我不太确定如何更改它，以便它使用Python 2.7版本？ - user1960836

@user1960836：坚持使用2.6版本。打开您添加了[funnelweb]部分的buildout.cfg文件。在recipe = funnelweb行下面添加一行eggs = ordereddict。这将确保它可用并已导入。重新运行buildout。 - Martijn Pieters
