Question

Estou tentando instalar o imagemagick e no meu MacOSX do Snow Leopard com homebrew.

quando eu corro:

sudo brew install imagemagick

quebra neste ponto com o seguinte log de erros.

Answer 1

Eu reinstalei libjpeg daqui e depois desvinculei e vinculei jpeg :

brew unlink jpeg
brew link jpeg

Corrigido o erro. Espero que isso funcione para você.

    

Answer 2

O que resolvi para mim foi atualizar o brew e depois instalar o imagemagick:

• brew update
• brew install imagemagick
