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

我安装了文档说需要的三个模块。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。当我现在先导入 xml2dict 然后导入 fred 时，我得到了完全相同的错误。

我很难学会在 Python 中安装模块，但我想我终于弄明白了。我似乎无法在这里找到我做错了什么，并且可以使用一些帮助。谢谢！

对于 Zach：这是我目前遇到的问题：

  File "<pyshell#3>", line 1, in <module>
    fred.series('GNPCA')

I'm the developer of the fred package. This is completely my fault — I had the setup.py file incorrectly configured, and I just pushed an update that should take care of this issue. Sorry for the confusion!

一般安装模块的提示：

通常最简单的方法是使用pipor easy_install（或二进制安装程序，如果有的话） - 这样您所需要做的就是easy_install fred自动下载所需的所有内容（只要配置正确）。

查看http://pypi.python.org/pypi/setuptools上的 setuptools并为您的适当操作系统版本安装它。然后，您将获得一个名为的命令，该命令easy_install将根据您的操作系统/设置安装在某个位置（尽管文档确实提到了位置）。[你也可以easy_install pip作为pip有效easy_install的继任者]

Then hopefully, all you need to do is easy_install fred (which will automatically find at http://pypi.python.org/pypi/fred), and it will download the latest version and all dependencies for you. Fire up your interpreter and import fred should "just work".
