导入quandl模块时出现问题
导入quandl模块时出现问题
提问于 2019-07-09 00:10:46
我正在尝试使用一些Quandl数据集创建一个数据科学项目，但在导入时收到一个错误。
正如我所知道的，quandl应该全部以小写形式导入，正如文档中所述的here和here，我的导入如下所示：
import quandl错误：
ModuleNotFoundError: No module named 'quandl'我使用pip install quandl安装了quandl。我的pip列表输出是：
Package Version

wincertstore 0.2我没有pip3，因为我是通过我的Anaconda安装来安装Python的。我正在为这个项目创建的虚拟环境中运行Jupyter Notebook。如您所知，python --version的输出是：
Python 3.7.3当我尝试使用import quandl运行一行python脚本时，出现了奇怪的部分。这一次程序运行没有错误，这意味着ModuleNotFoundError: No module named 'quandl'的原因是jupyter笔记本，它不能正确地找到quandl模块。
作为最后一个资源，我尝试在jupyter笔记本中安装quandl：
!pip install quandl

当您想要确保使用的是与该解释器关联的pip版本时，您可以使用pip，使用模块语法，而不是使用独立的CLI。
python -m pip install quandl
或者，由于您使用的是Conda，您也可以尝试使用conda命令行界面安装quandl。
conda install quandl (或者conda的任何包名)。
