I'm trying to install Imagemagick via brew, and I get this message upon installation:
Warning: imagemagick-6.8.6-3 already installed, it's just not linked
When I attempt to link it via brew link, I get this:
brew link imagemagick
Warning: Could not link imagemagick. Unlinking...
Linking /usr/local/Cellar/imagemagick/6.8.6-3...
Error: File exists - /usr/local/etc
Ideas?? I've tried:
'brew link -f imagemagick'
without luck (I get the same error message as above). It was suggested here: Brew linking with ImageMagick
According to brew update, I'm up to date. Brew doctor returns this:
Warning: You have MacPorts or Fink installed:
/Users/user_name/.rvm/bin/port, /opt/local/bin/port
This can cause trouble. You don't have to uninstall them, but you may want to
temporarily move them out of the way, e.g.
sudo mv /opt/local ~/macports
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
imagemagick
You need to remove the imagemagick file in /usr/local/etc
so that brew can write a new one there.
The old file was placed there by something else than brew. Possibly another package manager.
UPDATE 2015.03.07: as Chords indicated in a comment above it may be necessary to remove the folder entirely. (Although setting the correct permissions and groups may be an equivalent measure.)
