Ruby gem rmagick不会安装在Mac OS X上

Question

我知道这个问题早已被提出过很多问题,但没有一个解决方案适合我,我现在真的很绝望.

我正在尝试使用gem安装rMagick来安装侨民.我已经通过自制软件安装了imagick,并且在尝试运行gem install rmagick时收到此错误:

ERROR:  Error installing rmagick:
    ERROR: Failed to build gem native extension.

我对宝石和自制软件不是很有经验,我想知道是否有人可以帮助我.

Answer 1

在尝试安装gem之前运行此命令(使用自制软件).

brew install imagemagick

Answer 2

这是使用自制软件的破坏性较小的版本,rmagic也不能与imagemacigk版本7一起使用

ImageMagick版本6.4.9或更高版本(6.×.x).版本7尚不支持; ETA 2019年4月(https://github.com/rmagick/rmagick/pull/299)

.你可以从www.imagemagick.org获得ImageMagick.所以用brew尝试这个

brew install imagemagick@6
PKG_CONFIG_PATH=/usr/local/opt/imagemagick@6/lib/pkgconfig gem install rmagick
