Asset Precompile on Amazon Linux

Question

I installed locomotivecms app on a small amazon linux instance. I ran following to precompile the assets:

bundle exec rake assets:precompile

It's been like half an hour and the assets are still precompiling. Following is what I have on the terminal so far:

[ec2-user@domU-12-31-39-09-15-88 locomotivecms]$ bundle exec rake assets:precompile

Do the which commands mean that time is being spent finding the rake executable for each file that is getting precompiled?

Answer 1

Seems like you do not have imagemagick installed.

Depending on your distro, it should be either sudo yum install ImageMagick ImageMagick-devel or sudo apt-get install imagemagick.

You can test it whether it installed successfully by issuing the commands convert or identify.

However, the documentation recommends that your precompile on your own local machine, not on the remote server. Meaning, you issue bundle exec rake assets:precompile on your own machine first. That would avoid having to precompile on the remote server.
