python3连接Mysql错误

环境：win10-x64/python3.4.3/MySql5.7.10

python连接MySql服务器时，无论使用pymysql还是mysql-connector都无法正常连接,提示 Unknown database

如下

conn = pymysql.connect(user='root', password='password', database='test')Traceback (most recent call last):  File "<stdin>", line 1, in <module>  File "C:\Python34\lib\site-packages\pymysql\__init__.py", line 88, in Connect    return Connection(*args, **kwargs)  File "C:\Python34\lib\site-packages\pymysql\connections.py", line 678, in __init__    self.connect()  File "C:\Python34\lib\site-packages\pymysql\connections.py", line 890, in connect    self._request_authentication()  File "C:\Python34\lib\site-packages\pymysql\connections.py", line 1097, in _request_authentication    auth_packet = self._read_packet()  File "C:\Python34\lib\site-packages\pymysql\connections.py", line 965, in _read_packet    packet.check_error()  File "C:\Python34\lib\site-packages\pymysql\connections.py", line 394, in check_error    err.raise_mysql_exception(self._data)  File "C:\Python34\lib\site-packages\pymysql\err.py", line 120, in raise_mysql_exception    _check_mysql_exception(errinfo)  File "C:\Python34\lib\site-packages\pymysql\err.py", line 115, in _check_mysql_exception    raise InternalError(errno, errorvalue)pymysql.err.InternalError: (1049, "Unknown database 'test'")
