python - 在Python中使用FRED API遇到问题-无法加载模块

我正在尝试将此API用于美联储经济数据（FRED）：
https://github.com/zachwill/fred

我安装了文档要求的三个模块。我收到此错误：

import fred

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import fred
  File "build\bdist.win32\egg\fred\__init__.py", line 1, in <module>
    # Dummy file to make this a package.
  File "build\bdist.win32\egg\fred\fred.py", line 21, in <module>
ImportError: cannot import name xml2dict

然后，我安装了xml2dict并再次安装了fred。现在，当我先导入xml2dict然后再导入fred时，我得到了完全相同的错误。

我很难学习用Python安装模块，但以为我终于弄明白了。我似乎在这里找不到我在做什么错，可以寻求帮助。谢谢！

对于Zach：这是我目前遇到的问题：

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    fred.series('GNPCA')
  File "build\bdist.win32\egg\fred\api.py", line 90, in series
    return Fred().series(path, **kwargs)
  File "build\bdist.win32\egg\fred\core.py", line 100, in series
    return self.get('series', path, **kwargs)
  File "build\bdist.win32\egg\fred\core.py", line 36, in get
    request = requests.get(url, params=params)
  File "C:\Python26\lib\site-packages\requests-0.13.2-py2.6.egg\requests\api.py", line 54, in get

    r.send(prefetch=prefetch)

    raise ConnectionError(e)
ConnectionError: HTTPConnectionPool(host='api.stlouisfed.org', port=80): Max retries exceeded with     url: /fred/series?series_id=GNPCA&api_key=

最佳答案

我是fred包的开发人员。这完全是我的错—我错误地配置了setup.py文件，并且我刚刚推送了一个应解决此问题的更新。对困惑感到抱歉！
