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.

Answer 1

你应该先安装 ImageMagick：

sudo apt-get install imagemagick libmagickcore-dev libmagickwand-dev

Answer 2

在 Mac 上，我使用了 brew install imagemagick。

这让我可以顺利运行gem install rmagick -v '2.13.2'。

Answer 3

试试

$ export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH"

或

$ export PKG_CONFIG_PATH="/opt/local/lib/pkgconfig:$PKG_CONFIG_PATH"

然后$ gem install rmagick 应该可以工作
