'Can't import MongoClient

I am unable to do this:

from pymongo import MongoClient

I get:

>>> import pymongo
>>> from pymongo import MongoClient
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name MongoClient
>>> 

I am able to import pymongo without issues.

I am running mongodb 2.2.3 and Python 2.7.

I've also tried this:

>>> connection = pymongo.MongoClient()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'MongoClient'
>>> 

What am I doing wrong?

According to docs, MongoClient was introduced in version 2.4. As you installed pymongo from your distribution repository, it's quite possible it's not the most recent version. Try installing it via PiP (remove the one you have installed first):

pip install pymongo

If you had named your script pymongo.py, which masks the pymongo module from which you are importing.

Rename your script to something else like xyz.py (and delete the pymongo.pyc file if one was created next to it).

I would like to suggest more robust answer:

pip show pymongo

now see where it direct you and from there simply remove the pymongo directory

rm -rf <the dir where pymongo lay>/pymongo*

Now, you can safely install pymongo again:

pip install pymongo

This problem may occur if you have multiple .py programs in the current working directory. Deleting them solved my error. I am not sure of the reason though.

yes it's true you need to update use, check the upgrade section says http://api.mongodb.org/python/current/installation.html

   easy_install -U pymongo

If you used pymongo.Connection and encountered error, you should know that after the new updates, you should use pymongo.MongoClient instead. I had this issue so hopefully this will be helpful to someone else.

I had the same problem on Ubuntu 16.04.
This solved my problem:

sudo apt-get install build-essential python-dev

sudo apt-get install python-pip

sudo pip install pymongo

Python Script

Try it once, into python script run following statement

# try.py

import pymongo

If above statement didn't throw any exception then you need to install pymongo-2.4, if existing pymongo verion is 2.3

Open terminal

First you need to uninstall old pymongo version

pip uninstall pymongo

Then use following commands to install pymongo-2.4

wget http://pypi.python.org/packages/source/p/pymongo/pymongo-2.4.tar.gz
tar xzf pymongo-2.4.tar.gz
cd pymongo-2.4
python setup.py install

Worked for me for conda env

pip uninstall pymongo

then

pip install pymongo

Make sure your python source file is not called pymongo.py

Solution 11:[11]

Change filename from pymongo.py to something else.

Solution 12:[12]

You have a file named queue.py in your project folder. Rename that file, and that should fix the problem.

For newer version of pymongo, you don't need to import MongoClient. Do the following:

import pymongo

client = pymongo.MongoClient("localhost", 27017)
db = client.test_database
db.test_table

You'll get:

Collection(Database(MongoClient(host=['localhost:27017'], document_class=dict, tz_aware=False, connect=True), 'test_database'), 'test_table')
