brew install mongodb error: Cowardly refusing to `sudo brew install' Mac OSX Lion

Question

I am not sure why I\'m getting this error:

$ brew install mongodb
==> Downloading http://fastdl.mongodb.org/osx/mongodb-osx-x86_64-2.0.4.tgz
#############         


        

Answer 1

The lazy (brew) way:

ls -al /usr/local/bin/brew #confirm brew ownership
sudo chown root:wheel /usr/local/bin/brew
sudo brew install mongodb
sudo chown <your user>:<your group> /usr/local/bin/brew  #revert ownership

The non-brew way:

• Download mongodb distribution from 10gen: http://www.mongodb.org/downloads
• Install files in /usr/local/bin/
• Create a config file in /etc/mongo.conf (minimum, tell it where to store data, and probably tell it to bind only to localhost): http://www.mongodb.org/display/DOCS/File+Based+Configuration
• Create a startup script that calls mongod -f /etc/mongo.conf

Answer 2

I keep hitting this same problem over and over with different brew packages (today it was ImageMagick), so I keep coming back to this page. I'm just going to leave my version of the above instructions for myself, and maybe someone else will find it handy too

ls -al `which brew` # note user/group
sudo chown root:wheel `which brew`
sudo brew install <package name>
sudo chown <your user>:<your group> `which brew` # revert ownership

using which brew in back ticks substitutes your path to brew.

(and how do I escape backticks?)

Answer 3

I kept getting this error before realizing-- I WAS SUDO SU'd!

In other words, I had a root prompt and was trying to run brew install . Do not try to install using brew if your command prompt has a # at the end.

I feel dumb about it, but maybe this will help someone else.
