I decided to post this in English because other people may be also struggling with the issue.
When I installed pymongo (Python MongoDB client) 3.7.2 for Python 2.7 on Debian 9, I found a strange phenomenon. Writing the following script, saved it as ‘copy.py’ and run by
$ python2 copy.py
but it didn’t work and simply says
ImportError: cannot import name MongoClient
I googled for hours and tried provided many solutions but no luck. The code is very simple.
from pymongo import MongoClient client = MongoClient('localhost')
After all, the problem was the file name ‘copy.py’! When I changed the file name to a different one, the issue was resolved! Curious.
But in this old post on stackoverflow, Kavya_D was suggesting there seemed some kind of name conflict problem in a pymongo’s name space. Bingo! I hope this “strange behavior” will be officially clarified somewhere!
