提供的mongoengine节点名或servname或未知

Question

I am trying to connect to my heroku mongo database. My connecting URL looks like this

I've replaced my actual username/password in the example below.

mongodb://username:password@ds135522.mlab.com:35522/heroku_brpg2n9r

I then have my config set up like this:

mongo_uri = os.environ.get('MONGOLAB_URI')

if mongo_uri:

        MONGODB_SETTINGS = {
            'db': mongo_uri.split('/')[-1],
            'host': mongo_uri
        }
    else:
        MONGODB_SETTINGS = {
            'db': 'local',
            'host': '127.0.0.1'
        }

I then export MONGOLAB_URI=mongodb://username:password@ds135522.mlab.com:35522/heroku_brpg2n9r

When I try an connec to database it gives me the following error:

ServerSelectionTimeoutError: heroku_brpg2n9r:27017: [Errno 8] nodename nor servname provided, or not known

Looks like it had to do with my mongoengine version. I installed these modules and it started working as expected:

flask-mongoengine==0.7
mongoengine==0.8.7
pymongo==2.8.1
