Pandasql: sqldf执行错误

Question

我想使用pandasql执行sql查询"SELECT 1“。但是有一个错误：

 Traceback (most recent call last):

   File "C:\Users\AdminVAIO\Documents\Visual Studio
 2013\Projects\crm\crm\crm.py", line 47, in <module>

     print(ps.sqldf(s, locals()))

   File "C:\Python34\lib\site-packages\pandasql\sqldf.py", line 155, in
 sqldf

     return PandaSQL(db_uri)(query, env)

   File "C:\Python34\lib\site-packages\pandasql\sqldf.py", line 61, in
 __call__

     result = read_sql(query, conn)    

File "C:\Python34\lib\site-packages\pandas\io\sql.py", line 421, in read_sql

     coerce_float=coerce_float, parse_dates=parse_dates)    
File "C:\Python34\lib\site-packages\pandas\io\sql.py", line 1046, in read_sql

      cursor = self.execute(*args)    
 File "C:\Python34\lib\site-packages\pandas\io\sql.py", line 1025, in execute

     cur = self.con.cursor()

 AttributeError: 'Connection' object has no attribute 'cursor'

 Press any key to continue . . .

下面是代码(Python3.4，pandasql 0.7.1，熊猫0.14.1)：

import pandas as pd
import pandasql as ps

s = """
SELECT 1
"""
print(ps.sqldf(s, locals()))

帮帮我求你了！

Answer 1

这对我起了作用：

pip install -U pandasql

Answer 2

现在，它起作用了！

我刚安装了0.17.0而不是0.14.1
