如何在Ubuntu 10.04上安装rmagick？

到目前为止，这是我所做的：

sudo apt-get install imagemagick libmagickcore-dev

这并没有引发任何错误，因此我认为ImageMagick安装得很好。然后我尝试安装gem：

sudo gem install rmagick

这导致以下错误：

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

Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/rmagick-2.13.1 for inspection.

在Ubuntu 10.04上安装rmagick时需要做什么？

我认为您还必须从ubuntu归档文件安装libmagickwand-dev：

sudo apt-get install libmagickwand-dev

该软件包包含MagickWand.h文件。

须藤apt-get install libmagickwand-dev imagemagick

我按照以下步骤从源进行构建

> wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz
> tar -xzvf ImageMagick.tar.gz
> ./configure --prefix=/usr/local --with-x=no --disable-static --with-modules --without-perl --without-magick-plus-plus --with-quantum-depth=8 --disable-openmp
> make
> sudo make install
> sudo /sbin/ldconfig /usr/local
> sudo ln -f /usr/local/bin/Magick-config /usr/bin/Magick-config
> sudo PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/ gem install rmagick

结果

Building native extensions.  This could take a while...
Successfully installed rmagick-2.13.1

我遇到了类似的问题，并且遇到了以下帖子：http : //www.question-defense.com/2010/05/18/centos-linux-cant-install-rmagick-2-7-0-cant-find-magick -配置

安装libmagick9-dev之后，我可以毫无问题地安装rmagick gem。希望这可以帮助。

1. aptitude install imagemagick
2. aptitude install perlmagick

按照这些说明。
