numpy的简单导入错误

Question

我的代码：

import pandas as pd
import Quandl
import numpy

df = Quandl.get('WIKI/GOOGL')
print(df.head())

错误是：

Traceback (most recent call last):
  File "C:/Users/saeed/IdeaProjects/AI/q.py", line 1, in <module>
    import pandas as pd
  File "C:\Users\saeed\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pandas\__init__.py", line 19, in <module>
    "Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']

这是什么意思，我该如何解决它。我正在努力学习机器学习，而且我已经遇到了问题：）。
