安装了熊猫数据器，但不能调用。

Question

我在Python3.6中使用Windows，到目前为止，在许多其他包中运行都没有问题。

我正在尝试安装和使用熊猫数据中心，但是在我成功安装它之后：

当尝试在pycharm / jupyter中运行它时，我收到如下消息：

ModuleNotFoundError:没有名为“pandas_datareader”的模块

当我在cmd命令中运行pip3 list时，我可以看到它已经安装了(熊猫(0.22.0)、熊猫-datareader (0.5.0))。

关于这个问题，我看了很多答案，但还是解决不了。此外，我确信该目录已添加到windows路径。

Answer 1

在每个环境中，运行一个快速程序：

import sys 
for p in sys.path: 
    print(p). 

将这些路径与pip3安装pandas_datareader的位置进行比较，即c：\python36 36\lib\site-packages

您可能需要将其分别安装到PyCharm和jupyter中。
