I have been following instructions from official documentation.
I tried to repair it, but it didn't help.
mongod --repair

I was also trying to install locales, but it also didn't help.
How can I get around this and install mongodb? What can be the error?

Answer 1

After successfully installing MongoDB (via Homebrew) on Yosemite, these instructions were displayed:
To have launchd start mongodb at login:
ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents
Then to load mongodb now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Or, if you don't want/need launchctl, you can just run:
mongod --config /usr/local/etc/mongod.conf
"/usr/local/etc/mongod.conf" contains the "dbpath" argument. After reviewing that file I was also able to start MongoDB as follows:
$ mongod --dbpath /usr/local/var/mongodb
On a Linux environment your paths are probably different, but I hope this helps answer your question and provides you with some direction to solve your problem.
