Ruby on rails Ubuntu-无法安装RMagick

如何将RMagick gem安装到Ubuntu？我在这里找到了一些线程，其中一些直接指向Ubuntu系统上的安装，但没有一个适合我

这是我运行sudo gem install rmagick时得到的输出

Building native extensions.  This could take a while...

Can't install RMagick 2.13.2. Can't find MagickWand.h.

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

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

它在AmazonEC2服务器上。 如果我尝试运行gem install rmagick，我会

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

你能帮我解决这个问题吗

多谢各位

但是上面仍然有相同的错误消息。

查看错误输出，您缺少了rmagick的一个依赖项。试一试

sudo apt-get install libmagickwand-dev sudo apt get安装libmagickwand dev 然后试试看

gem install rmagick gem安装rmagick

第二个问题可能是由于权限问题。更多关于您所采取的步骤的信息将有助于我们为您提供更好的答案。

您应该发布您尝试过但不起作用的内容，否则人们会再次给您所有相同的答案。关于这一点，superuser已经有一个Q/a，请参阅更新操作。几天前我使用了bitnami实例，我没有安装rmagick，你需要更新版本吗？您可以尝试将Gemfile中的版本设置为与instance

gem'rmagick'、\u instance'

中的\u version\u相同。我想您可以使用

rmagick-v

@juanpstatas在实例中获得版本。好吧，如果我在控制台

rmagick-v

中运行，我得到

对不起，找不到的命令已崩溃！请在以下地址提交错误报告：https://bugs.launchpad.net/command-not-found/+filebug请在报告中包含以下信息：未找到命令版本：0.2.44。我不确定权限，是否有类似权限重置的内容？或者只是在它前面添加
sudo
：）你就是那个人！
