To install Brew's ImageMagick and fix its Symlink
Assume you installed Imagemagick by
brew install imagemagick
but it does not get into your PATH. For example, I run unsuccessfully
compare
since imagemagick is not in PATH: -bash: compare: command not found
.
The command ls -l /usr/local/bin/compare
gives
ls: /usr/local/bin/compare: No such file or directory
My .bash_profile
if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi
# http://apple.stackexchange.com/a/53058/15504
export PATH=/usr/bin:/usr/local/bin:/opt/local/sbin:$PATH
Echoing $PATH
gives
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/git/bin:/usr/texbin
which seems to be ok because /usr/local/bin/
there.
ImageMagick in my system - answers to 4ae1e1's answer
The command brew --prefix
gives /usr/local
so ok.
The command brew info imagemagick
gives

I run the command brew link imagemagick
and get
Linking /usr/local/Cellar/imagemagick/6.9.0-3...
Error: Could not symlink bin/convert
Target /usr/local/bin/convert
already exists. You may want to remove it:
rm '/usr/local/bin/convert'
To force the link and overwrite all conflicting files:
brew link --overwrite imagemagick
To list all files that would be deleted:
brew link --overwrite --dry-run imagemagick
This seems to be strange. How can you solve this problem?
I run the command brew reinstall imagemagick
and get

🍺 /usr/local/Cellar/imagemagick/6.9.0-3: 1440 files, 22M
so something wrong in symlinking.
How can you solve the error about symlink?
Solution 1:
A list of things to try, in order (I'm writing an answer instead of a comment for better formatting). Run hash -r
after each step (assuming you're in bash; do rehash
instead for zsh; or you can always open a new shell).
Run
brew --prefix
and see if the output is/usr/local
. If not, yourbrew
is not installed to/usr/local
! Add$(brew --prefix)/bin
to you$PATH
.Run
brew info imagemagick
and make sure it's actually installed; maybe you had an error during installation and it was simply not installed successfully.Run
brew link imagemagick
to symlink to/usr/local/bin
; maybe the executables weren't symlinked correctly (for some reason);Run
brew reinstall imagemagick
to reinstall.If it still doesn't work, show us the output of
brew list imagemagick
and we'll see what's wrong.
