python-2.7 - Spyder 中的 Python Quandl

Question

Spyder 与 numpy 和 pandas 配合得很好，但使用 Quandl 时出现以下错误(在 spy 程序中):

>>> import Quandl
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named Quandl

但是从终端 Quandl 安装没有问题:

$ sudo easy_install quandl

我还可以直接从终端使用该库(在 python2.7 中):

$ python2.7

对于 Spyder 为何不与 Quandl 合作有任何意见吗？

肯定有人在我之前尝试过攀登这座山。

在浏览 stackoverflow 时并未发现解决方案，但 google 小组向我指出了解决方案:

Answer 1

我最初编写了Quandl(大写)并收到了错误，就像您所做的那样。它对我来说是小写的(import quandl)。

quandl 主页上的 python 代码在这一点上是错误的:

Quandl.get("OFDP/FUTURE_VX6", trim_start="2004-05-19", trim_end="2014-10-16")

因为他们使用大写的 Q。
