Installing MongoDB

Question

I get this error when installing MongoDB on OSX, even though the second time I tried it with sudo command. Any thought?

==> Checking out tag r3.0.3
==> ./build.sh
==> /usr/local/opt/scons/bin/scons install --prefix=/usr/local/Cellar/mongodb/3.0.3 -j4 --osx-version-min=10.9 --cc=/usr/bin/clang --cxx=/usr/bin/clang++ --use-new-tools
Error: Permission denied - /usr/local/var/mongodb
Monas-MacBook-Pro:meanio mona$ sudo brew install mongodb

Error: Cowardly refusing to `sudo brew install`
You can use brew with sudo, but only if the brew executable is owned by root.
However, this is both not recommended and completely unsupported so do so at
your own risk.

Answer 1

It's a permissions problem. The solution being:

sudo chown -R `whoami` /usr/local/var/mongodb

Per the comment:

Try creating the directory, prior to setting ownership:

sudo mkdir /usr/local/var/mongodb && sudo chown -R `whoami` /usr/local/var/mongodb

Answer 2

I just open /usr/local/ via finder and manually create folder with name var. Mac asked for a password. After that I successfully install MongoDB.
