Como resolver o conflito do Ruby on Rails ImageMagick?

Question

Estou tentando instalar refinerycms , um Ruby on Rails CMS no Ubuntu 10.04 LTS. Eu corro rails server e recebo a seguinte exceção:

carcher@carcher-laptop:~/Code/tgc$ rails server

Eu criei e instalei o ImageMagick 6.6.4 a partir do código-fonte seguindo as instruções aqui e ANTES DE fiz isso removi as ferramentas do ImageMagick que estavam pré-instaladas no Ubuntu, para evitar conflitos. Mas ainda pareço ter esta versão 6.5.7 ao redor.

Acho que minha pergunta é como eu removo / desabilito ImageMagick 6.5.7-8 ?

Estou em funcionamento! Solução publicada aqui no Stack Overflow.

    

Answer 2

É provável que você tenha instalado o imagemagick 6.5.7 para / usr / local, se não puder encontrá-lo na lista de pacotes.

Tente which convert para ver onde os binários do imagemagick estão localizados. ( convert é um dos utilitários fornecidos com o imagemagick.) Tente também convert --version para ver qual versão está ativa. Se você obtiver uma versão diferente do que Ruby / Rails está vendo, verifique sua configuração de projeto para ter certeza de que você não tem nenhum caminho extra que possa estar procurando. Além disso, certifique-se de que o imagemagick não foi instalado no diretório do Rails. ; Eu acho que pode tentar incluir coisas lá também.
