Pakiet MagickCore nie został znaleziony w ścieżce wyszukiwania pkg-config

Question

Próbowałem zainstalować rmagick i zawsze prosi o skonfigurowanie PKG_CONFIG_PATH.

To zdarzyło się wiele razy dla mnie, więc publikuję to jako problem i odpowiadam sobie za każdego, kto ma ten sam problem.

Answer 1

rmagick gem nie jest w stanie znaleźć PKG_CONFIG_PATH podczas instalacji. Musimy określić, gdzie znajduje się ścieżka do ImageMagick. Zawsze lepiej jest dodać w bash.

Answer 2

Mam ten sam problem. To praca dla mnie (Ubuntu):

sudo apt-get install libmagickwand-dev 

Answer 3

CentOS

yum install ImageMagick-devel
