ConfigurationError: Server at 127.0.0.1:27017 reports wire version 0, but this version of PyMongo requires at least 2 (MongoDB 2.6)

Question

I am trying to build an application with mongoDB and Python Flask. While running the application, I am getting below error:

ConfigurationError: Server

Answer 1

It's pretty annoying and weird issue.

But this problem is solved with just downgrading pymongo library for me.

pip install pymongo==3.4.0

Found answer in this : http://d-prototype.com/archives/10939

Answer 2

This works for me:

1. sudo pip3 uninstall pymongo

2. sudo apt-get install python3-pymongo

I hope that works for someone else, regards.

Answer 3

I am having the same issue using version 2.4.10 on a Raspberry Pi 3. I found interesting information here: https://jira.mongodb.org/browse/SERVER-26715

According to the above Jira task, it seems that this is a bug of MongoDB that was fixed in version 3.4. However, I found that comment stating that 3.4 is not supported on Raspbian because it is a 32-bits OS. This is confirmed here... we can only install 3.2 on Raspbian now apparently.

An alternative would be to install 64bits SuSE on the Pi or run MongoDB 3.4 in Docker.

Let me know if you have found something else...

Answer 4

loose_srv_version = LooseVersion(client.server_info()['version'])

loose_driver_version = LooseVersion(PyMongoVersion)

if loose_srv_version >= LooseVersion('3.2') and loose_driver_version <= LooseVersion('3.2'):
    module.fail_json(msg=' (Note: you must use pymongo 3.2+ with MongoDB >= 3.2)')

elif loose_srv_version >= LooseVersion('3.0') and loose_driver_version <= LooseVersion('2.8'):
    module.fail_json(msg=' (Note: you must use pymongo 2.8+ with MongoDB 3.0)')

elif loose_srv_version >= LooseVersion('2.6') and loose_driver_version <= LooseVersion('2.7'):
    module.fail_json(msg=' (Note: you must use pymongo 2.7+ with MongoDB 2.6)')

elif LooseVersion(PyMongoVersion) <= LooseVersion('2.5'):
    module.fail_json(msg=' (Note: you must be on mongodb 2.4+ and pymongo 2.5+ to use the roles param)')
