【问题描述】：

我在一个小型 amazon linux 实例上安装了 locomotivecms 应用程序。我跑了以下来预编译资产：

bundle exec rake assets:precompile

已经有半个小时了，资产仍在预编译中。以下是我目前在终端上的内容：

[ec2-user@domU-12-31-39-09-15-88 locomotivecms]$ bundle exec rake assets:precompile
/home/ec2-user/.rvm/rubies/ruby-1.9.3-p448/bin/ruby /home/ec2-user/.rvm/gems/ruby-1.9.3-p448/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets

which 命令是否意味着要花费时间为每个正在预编译的文件查找 rake 可执行文件？

标签： ruby-on-rails amazon-ec2 precompile

【解决方案1】：

好像你没有安装 imagemagick。

根据您的发行版，它应该是 sudo yum install ImageMagick ImageMagick-devel 或 sudo apt-get install imagemagick。

你可以通过convert或者identify来测试它是否安装成功。

但是，文档建议您在自己的本地机器上进行预编译，而不是在远程服务器上。意思是，您首先在自己的机器上发出bundle exec rake assets:precompile。这样可以避免在远程服务器上进行预编译。

谢谢。正如你提到的 Imagemagick 丢失了。安装后，我不再看到 which: no convert, which: no identify 消息。
