import pandas as pd
import numpy as np
from pandas import Series, DataFrame
df = pd.DataFrame()
执行后输出：
Traceback (most recent call last):
File "D:/Python/dayline.py", line 1, in <module>
import pandas as pd
File "C:\Python27\lib\site-packages\pandas\__init__.py", line 18, in <module>
raise ImportError("Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']
而且之前是能够运行的 晕
