Cannot start meteor and mongo on windows 10?


I get an error


Error: URL must be in the format mongodb: // user: pass @ host: port / dvname
I do not understand, because of what is happening. I tried to install as I tried so:

set MONGO_URL="mongodb://" && meteor --port 8031 --settings local-settings.json
set MONGO_URL="mongodb://root:password@" && meteor --port 8031 --settings local-settings.json

Set in settings file

    "MONGO_URL": "mongodb://root:password@localhost:7777/zenmarket"
    "MONGO_URL": "mongodb://@localhost:7777/zenmarket"

mongod port 7777

Windows 10 64

Meteor v1.3.4.1

Mongo shell v3.2.7

I’m desperate
