mongodb - Running Meteor on localhost fails with RangeError: port should be >= 0 and < 65536: NaN

Question

I am running a project on localhost using node and Mongodb, but it fails with an error as soon as I try to create a collection on the database.

I am building the project with this script:

cd ~/Meteor/daily-reminder
meteor build ~/build-output-daily-reminder --server=http://localhost
cd ~/build-output-daily-reminder
tar -xvzf daily-reminder.tar.gz
rm daily-reminder.tar.gz
cd ~/build-output-daily-reminder/bundle
(cd programs/server && npm install)
export MONGO_URL='mongodb://username:password@http://localhost:27017/daily-reminder'
export ROOT_URL='http://localhost/'
export PORT='3000'
echo "now run node main.js"
node main.js

(I use my actual mongodb username and password in the real code).

The project builds fine, but node won't run. It generates this error:

now run node main.js
/home/shelagh/build-output-daily-reminder/bundle/programs/server/node_modules/fibers/future.js:245
                        throw(ex);
                              ^

If I use a newly-created Meteor project then node runs ok. But it fails as soon as I add this line to start of my js file:

Tasks = new Mongo.Collection("tasks");

It seems like there is some problem as soon as the server tries to communicate with the database. But I can't see anything wrong with my MONGO_URL: port is specified as 27017. From the error, it looks like the port isn't even being passed in.

I am using node v0.12.7 and MongoDB shell version: 2.4.9. I have started mongo by typing 'mongo' in a separate terminal window.

Your MONGO_URL is wrong, it redefines the protocol where you specify the host.

Change

export MONGO_URL='mongodb://username:password@http://localhost:27017/daily-reminder'

to

export MONGO_URL='mongodb://username:password@localhost:27017/daily-reminder'
