安装rmagick时出错:错误:无法构建gem原生扩展

Question

我想在我的本地机器上运行一个项目.我在Mac OS系统上安装了Ruby和Rails.它运作正常.我可以创建一个新项目,并且可以正常运行它而不会出现任何错误,但是当我尝试运行现有项目时,它说我们必须这样做bundle install.当我运行该命令时,我收到以下错误:

"An error occurred while installing rmagick (2.13.2), and Bundler cannot continue.
Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling."

当我运行gem install rmagick -v '2.13.2'它时给我以下错误:

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

Answer 8

根据错误日志，似乎缺少“Magick-config”。您需要安装 ImageMagik 或 GraphicsMagick。这些是您应该遵循的命令，这些命令取自RMagik 文档：

1) Go to http://www.imagemagick.org or http://www.graphicsmagick.org and download the latest version of the software to a temporary directory. the extract them :

- tar xvzf ImageMagick.tar.gz
- cd ImageMagick-x.x.x

- ./configure --disable-static --with-modules --without-perl --without-magick-plus-plus --with-quantum-depth=8

- make
- sudo make install

- sudo gem install rmagick
