我尝试通过在 cmd 提示符下运行以下代码来使用 pip安装Python Quandl 模块：

C:\Users\zeke\Desktop\Python\python.exe -m pip install quandl

模块开始下载和安装，直到出现错误消息：

C:\Users\zeke>C:\Users\zeke\Desktop\Python\python.exe -m pip install quandl

我按照文件路径“C:\Users\zeke\Desktop\Python\python35.zip\lib2to3\Grammar.txt”，文件完全存在。为什么我会收到此错误？

我能够通过将 .../Python/Python35.zip 提取到 .../Python 中名为“Python35.zip”的新目录来解决此问题。

但是现在我在尝试导入模块时收到错误。

>>> import quandl
