미티어 실행 시 Can't start Mongo server 에러 해결

이와 같은 에러가 났을 경우에 : 

Can't start Mongo server. MongoDB has an unspecified uncaught exception. This can be caused by MongoDB being unable to write to a local database. Check that you have permissions to write to .meteor/local. MongoDB does not support file systems like NFS that do not allow file locking. 

rm -rf .meteor/local/db

명령어 실행 후 다시 실행시킨다.
