La mia installazione imagemagick tramite brew sembra non aver creato correttamente i collegamenti simbolici.
$ convert -version
-bash: convert: command not found
Esecuzione
$ brew link -f imagemagick

Linking /usr/local/Cellar/imagemagick/7.0.7-22...
Error: Could not symlink include/ImageMagick-7/Magick++/Blob.h
/usr/local/include/ImageMagick-7/Magick++ is not writable.
Ho controllato Per installare Brew's ImageMagick e correggere il suo collegamento simbolico ma il problema risolto è rappresentato da collegamenti simbolici non funzionanti già presenti, non permessi.
Altre informazioni utili includono:
$ brew info imagemagick

Warning: "config" scripts exist outside your system or Homebrew directories.
'./configure' scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:

Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on

imagemagick
Nota il fusto non collegato in cantina.
Questo problema è risolvibile usando
$ sudo chown -R user:group ImageMagick-7/
ma mi piacerebbe davvero sapere cosa ha causato il problema originale e se ci sono soluzioni migliori.
