python - pymongo 或 VERSION 中不存在 FIND 方法？

<分区>

我正在尝试使用带有登台数据库的 pymongo 做一些简单的事情。所以像往常一样做第一件事

import pymongo
connection = pymongo.Connection(host = 'mongodb://username:password@alaki-staging.member0.mongolayer.com:37017,/dbname?safe=true&slaveOk=true&fsync=true&journal=true&ssl=true')

现在就

connection.find({})
> Traceback (most recent call last):
  File "D:\MypythonCode\test.py", line 7, in <module>
    connection.find({})
  File "C:\Python27\lib\site-packages\pymongo\database.py", line 769, in __call_
_
    self.__name, self.__connection.__class__.__name__))
TypeError: 'Database' object is not callable. If you meant to call the 'find' me
thod on a 'Connection' object it is failing because no such method exists.

C:\Python27>python.exe D:\MypythonCode\test.py > test.d
Traceback (most recent call last):
  File "D:\MypythonCode\test.py", line 7, in <module>
    connection.find({})
  File "C:\Python27\lib\site-packages\pymongo\database.py", line 769, in __call_
_
    self.__name, self.__connection.__class__.__name__))
TypeError: 'Database' object is not callable. If you meant to call the 'find' me
thod on a 'Connection' object it is failing because no such method exists.

甚至检查版本!？

connection.version()

Traceback (most recent call last):
  File "test.py", line 7, in <module>
    connection.version()
  File "C:\Python27\lib\site-packages\pymongo\database.py", line 769, in __call_
_
    self.__name, self.__connection.__class__.__name__))
TypeError: 'Database' object is not callable. If you meant to call the 'version'
 method on a 'Connection' object it is failing because no such method exists.
