Não consigo instalar o RMagick devido ao seguinte problema de dependência depois de tentar sudo apt-get install libmagick9-dev ( necessário de acordo com isso ) no Ubuntu 10.0.4:
Note, selecting libmagickwand-dev instead of libmagick9-dev Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:
The following packages have unmet dependencies:
libmagickwand-dev:
Depends: libmagickwand2 (= 7:6.5.7.8-1ubuntu1.1) but it is not going to be installed
Depends: libmagickcore2-extra (= 7:6.5.7.8-1ubuntu1.1) but it is not going to be installed
Depends: libmagickcore-dev (= 7:6.5.7.8-1ubuntu1.1) but it is not going to be installed
Tentando instalar o apt-get libmagickwand2, eu entendi:
> The following packages have unmet dependencies: libmagickwand2:
> Depends: libice6 (>= 1:1.0.0) but it is not installable
> Depends: libjpeg62 but it is not installable
> Depends: libmagickcore2 (>= 7:6.5.7.8) but it is not going to be installed
> Depends: libsm6 but it is not installable
> Depends: libtiff4 but it is not going to be installed
> Depends: libxt6 but it is not installable
Isso funciona:
sudo apt-get install imagemagick libmagickcore-dev libmagickwand-dev
de acordo com o comentário de dalibor-filus abaixo.
[ Resposta original - Ok, parece que resolvi isso com apt-get install imagemagick libmagickwand-dev , então libmagick9-dev não foi necessário. ]
Eu tive esse problema no Ubuntu 11.10, e a solução da @mahemoff não funcionou para mim. No final, eu desinstalei tudo do ImageMagick e compilei a versão mais recente do ImageMagick a partir do código-fonte, e depois o rmagick foi instalado bem.
Tente isso para o OSX: link
Isso funcionou muito bem para mim, onde apt-get e brew falharam
