You must specify a URI or set the MONGO_URI Flask config variable

[HailinRen]

When I try to run , I got the following error,
'''
mongo = PyMongo(app)
File "/usr/local/lib/python2.7/dist-packages/flask_pymongo/init.py", line 116, in init
self.init_app(app, uri, *args, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/flask_pymongo/init.py", line 146, in init_app
"You must specify a URI or set the MONGO_URI Flask config variable",
ValueError: You must specify a URI or set the MONGO_URI Flask config variable
'''

Any help?

I've tried to reproduce your error by messing with my mongodb settings, but I haven't had luck. So a few questions:

1. Do you have mongodb running?
2. Have you modified the default_config.py file? This file assumes that your mongodb server can be reached at localhost:27017
3. What version of pymongo do have?

I am using anaconda and have following packages
"
Flask 1.0.2
Flask-PyMongo 2.0.0
pymongo 3.7.0
"
After I add " app.config["MONGO_URI"] = "mongodb://localhost:27017/visipedia_annotation_toolkit" "before mongo = PyMongo(app), then it could work.
Thank you for your help!

In which file do we have to add this text? can you please tell the location of the file in Ubuntu.

Are you using the mongo_uri and then defining the value app.config["MONGO_URI"] =os.getenv("MONGO_URI")
if so then use dotenv and load_dotenv
