python - 导入quandl模块的问题

Question

我正在尝试使用一些 Quandl 数据集创建一个数据科学项目，但在导入时收到错误消息。

据我所知，quandl 应该全部以小写形式导入，正如文档在此处和此处所述，我的导入如下：

import quandl

错误：

ModuleNotFoundError: No module named 'quandl'

我使用pip install quandl. 我的点子列表输出是：

Package         Version

asn1crypto      0.24.0
certifi         2019.6.16

urllib3         1.25.3
wheel           0.33.4
wincertstore    0.2

我没有 pip3，因为我通过 Anaconda 安装安装了 Python。我正在为这个项目创建的虚拟环境中运行 Jupyter Notebook。众所周知，python --version输出是：

Python 3.7.3

当我尝试使用import quandl. 这次程序运行没有错误，这意味着原因ModuleNotFoundError: No module named 'quandl'是 jupyter notebook 无法正确找到 quandl 模块。

作为最后一个资源，我尝试在 jupyter notebook 中安装 quandl：

!pip install quandl
import quandl

输出：

试试pip3 install quandl。它通常适用于 Python 3.x
