Question

我在Ubuntu 16.04中使用Python 3.6。

从这个非常简单的程序：

import pandas_datareader.data as web
import datetime
amzn = web.DataReader("AMZN", "yahoo", datetime(2000,1,1), datetime(2015,1,1))

我得到了这个令人印象深刻的错误列表：

 Traceback (most recent call last):

我现在真的知道导致此错误的原因除了程序尝试导入pandas_datareader时发生的错误。

我是data_reader的新手，但我非常确定import命令在语法上是正确的。

有人能说出问题是什么吗？

Answer 1

我认为您已使用自己的argparse隐藏了Python模块/SAT/argparse.py。

第4行中的

/anaconda/lib/python3.6/unittest/main.py尝试导入argparse（标准Python模块），但您的模块（错误len(sys.argv) > 1:）会先跳转。

尝试将/SAT/argparse.py重命名为/SAT/my_argparse.py

PS尝试以不同方式命名您自己的脚本和目录，以便他们不会影响标准Python模块

Answer 2

试试这个：

import datetime

import pandas_datareader.data as web

amzn = web.DataReader("AMZN", "yahoo", datetime.datetime(2000,1,1), datetime.datetime(2015,1,1))

无法导入Pandas_Datareader
