尝试通过pip安装Quandl模块时出错

Question

我试图通过在cmd提示符下运行以下代码来通过pip安装Python Quandl模块 ：

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

该模块开始下载并安装，直到出现错误消息：

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

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\zeke\AppData\Local\Temp\pip-build-emddiyej\ndg-httpsclient\

我遵循文件路径“ C：\\ Users \\ zeke \\ Desktop \\ Python \\ python35.zip \\ lib2to3 \\ Grammar.txt”，该文件完全存在。 为什么会出现此错误？

Answer 1

通过将... / Python / Python35.zip解压缩到... / Python中名为“ Python35.zip”的新目录中，我得以解决此问题。

但是，现在尝试导入模块时收到错误。
