Pandas-datareader已安装，但无法调用

Question

我正在使用 Windows 和 Python 3.6，到目前为止，许多其他软件包都没有问题运行ning。

我正在尝试安装和使用 pandas-datareader，但在我成功安装之后：

当尝试在 pycharm / jupyter 中运行时，我收到：

ModuleNotFoundError: No module named 'pandas_datareader'

当我在 cmd 命令中运行 pip3 list 时，我可以看到它已安装 (pandas (0.22.0) pandas-datareader (0.5. 0)).

关于这个问题我看了很多答案，还是没能解决。另外，我确定该目录已添加到 windows 路径。

Answer 1

在您的每个环境中，运行一个快速程序：

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

将这些路径与安装 pip3 的路径进行比较 pandas_datareader，即 c:\python36\lib\site-packages

您可能需要将其单独安装到 PyCharm 和 jupyter
