Problems to run examples in Meteor

Fixing the problem,

meteor reset

Warning: This erases your local database.

meteor reset:

Assume that you get this error:

reset: Meteor is running.
 
This command does not work while Meteor is running your application.
Exit the running meteor development server.

Then look for meteor in your running processes:

ps -x | grep meteor

The following lines are output:

14877 pts/0 Sl 0:02 /usr/lib/meteor/mongodb/bin/mongod --bind_ip 127.0.0.1 --port 3005 --dbpath /home/sam/proto/.meteor/local/db
15022 pts/0 S+ 0:00 grep --color=auto meteor

Then  enter this:

kill -s KILL 14877
meteor reset
meteor

Now all are working…

This could be a alternative best solution:

It can be solved by Just removing .meteor/local/db/mongod.lock in the meteor project folder.  And  then meteor will run normally.
