Предположим, вы установили Imagemagick
brew install imagemagick
но это не попадает в ваш путь. Например, я бегу неудачно
compare
поскольку ImageMagick не в PATH: -bash: compare: command not found
.
Команда ls -l /usr/local/bin/compare
дает
ls: /usr/local/bin/compare: No such file or directory
Мой .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
Эхо $PATH
дает
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/git/bin:/usr/texbin
что, кажется, хорошо, потому что /usr/local/bin/
там.
ImageMagick в моей системе - ответы на 4ae1e1
Команда brew --prefix
дает /usr/local
так хорошо.
Команда brew info imagemagick
дает

Я запускаю команду brew link imagemagick
и получаю
Linking /usr/local/Cellar/imagemagick/6.9.0-3...
Error: Could not symlink 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
Это кажется странным. Как вы можете решить эту проблему?
Я запускаю команду brew reinstall imagemagick

так что-то не так в символических ссылках.
Как вы можете решить ошибку о символической ссылке?
type -a compare
и, ls -l /usr/local/bin/compare
как предложил Патрикс.
