我在一个小的amazon linux实例上安装了locomotivecms app。我跑了以下来预编译资产：
bundle exec rake assets:precompile
这已经过了半个小时，资产仍在进行预编译。以下是我到目前为止在终端上的内容：
[ec2-user@domU-12-31-39-09-15-88 locomotivecms]$ bundle exec rake assets:precompile

哪些命令意味着花时间为每个正在编译的文件找到rake可执行文件？
答案 0 :(得分：2)
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。
您可以通过发出命令convert或identify来测试它是否已成功安装。
但是，文档建议您在自己的本地计算机上预编译，而不是在远程服务器上。这意味着，您首先在自己的计算机上发出bundle exec rake assets:precompile。这样可以避免在远程服务器上进行预编译。
