Meteor: unexpected mongo exit code 100
Using meteor reset
erases all the data from your database. If you're worried about this then navigate to your project folder.
cd /path/to/my/project
Here you need to erase the mongodb.lock
file.
rm .meteor/local/db/mongodb.lock
Now you can run Meteor using the command,
meteor
Removing this file and folder worked for me:
rm -rf .meteor/local/db/mongod.lock .meteor/local/db/journal/
Mine was fixed in the end by running export LC_ALL=C
. Found the error through the debugging steps suggested in this post: https://stackoverflow.com/a/15752736/1820510
