Problems installing imagemagick

Question

Im trying to start my first refinery cms project, and am already having trouble. I am trying to get imagemagick going, and am getting errors. I looked on stackoverflow about changing permissions to my profile, or the directories that have problems, also uninstalling and reinstalling, but so far no luck. I was hoping maybe someone could walk me through fixing this. Thanks so much.

 Mac-Pro:local user$ brew install imagemagick
 Error: You must `brew link jpeg' before imagemagick can be installed
 Mac-Pro:local user$ brew link jpeg
 Linking /usr/local/Cellar/jpeg/8d... 
 Error: Could not symlink file: /usr/local/Cellar/jpeg/8d/bin/wrjpgcom
 /usr/local/bin is not writable. You should change its permissions.

Solution

After encouragement, here's my comment to the question as an answer.

The problem is that the directory Homebrew is trying to use isn't writable by the user running brew. To fix this, make the directory writable by that user.

sudo chown -R yourusename:admin /usr/local/bin

This recursively changes the ownership of all objects inside the /usr/local/bin directory to the user called yourusername. It assumes that your user is in the OS X administrator group.

If you're not sure of the username of your user, you can run the command whoami.

It looks like /usr/local/bin isn't writeable. Doing ls -la /usr/local will tell you the permissions of the bin directory (mine belongs to my user, in the admin group).

sudo chown -R yourusename:admin /usr/local/bin. This recursively changes the contents of bin to belong to the user yourusername in the group admin.

It might also be worth noting that the Xcode command line tools must be installed, too.

@JordanThornquest Sure, but the tools are a prerequisite for Homebrew. Installing those tools doesn't solve the problem in question.

sudo chown -R $(whoami):admin /usr/local
