You can find more details about this issue on this Gist: https://gist.github.com/richardsondx/10092890 I noticed that the environment is not mentioned in the rake task even though I mentioned it in production.rb. It could help to overwrite the prefix the command with RAILS_ENV=production
I tried to overwrite the task with:
namespace :deploy do
namespace :assets do
task :precompile do
on roles(fetch(:assets_roles)) do
within release_path do
with rails_env: fetch(:rails_env) do
execute :rake, "assets:precompile RAILS_ENV=production"
end
end
end
end
end
end
But it didn't overwrite it.
I was dealing with the same problem in my VPN on DigitalOcean and I had to create the swap memory. My VPS was killing the assets precompile process.
Before creating swap memory, you can check if your server is using some swap memory using htop. My server wasn't ...
Try this:
Create 1GB swap memory
sudo dd if=/dev/zero of=/usr/mem.swap bs=1M count=512
Use the swap memory created in the first step
sudo mkswap /usr/mem.swap
sudo swapon /usr/mem.swap
