Question

如何将RMagick gem安装到Ubuntu？我在SO上找到了一些线程，其中一些直接指出了Ubuntu系统上的安装，但它们都没有为我工作。

如果我运行 sudo gem install rmagick

，这是我得到的输出

Building native extensions.  This could take a while...
ERROR:  Error installing rmagick:

Can't install RMagick 2.13.2. Can't find MagickWand.h.
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib

Gem files will remain installed in /opt/bitnami/ruby/lib/ruby/gems/1.9.1/gems/rmagick-2.13.2 for inspection.
Results logged to /opt/bitnami/ruby/lib/ruby/gems/1.9.1/gems/rmagick-2.13.2/ext/RMagick/gem_make.out

它位于Amazon EC2服务器上。如果我尝试只运行 gem install rmagick ，我会得到

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions into the /opt/bitnami/ruby/lib/ruby/gems/1.9.1 directory.

请帮助我，如何解决这个问题？

非常感谢

编辑：我尝试了什么：

sudo apt-get install libmagickwand-dev

但上面仍然是相同的错误信息。

Answer 1

查看错误输出，您错过了rmagick的一个依赖项。试试

sudo apt-get install libmagickwand-dev

然后尝试

gem install rmagick

第二个问题可能是由于许可问题。有关您采取的步骤的更多信息将有助于我们为您提供更好的答案。
