[mattbrictson]

Without an error message it is hard to say what is going on. I see that the command being executed is bundle exec rake assets:precompile but I don't see anything after that in the logs you posted. There are many things that could go wrong. Asset complication is slow and resource intensive, so it is possible that the system is running out of memory. You could try logging into the machine via SSH separately while capistrano is running and use a command like top to see what is happening while the assets:precompile is seemingly stuck.

[amolplay]

@mattbrictson : Here are the complete capistrano logs

Error occured when assets:precompile executed. Server's memory is available. I think /releases/20200711132725 directory not creating for assets but not sure .

[mattbrictson]

Hmm that is frustrating. I don't have any ideas but could you try running the command manually via SSH instead of through cap? That might make the error more apparent.

[falegk]

Same issue.

capistrano-3.14.1
capistrano-rails-1.6.1

@mattbrictson for me this command is working properly via SSH

cd /var/www/app/releases/20200728173430 && ( export PATH="$HOME/.npm-packages/bin/:$PATH" 
NODE_ENVIRONMENT="production" RBENV_ROOT="$HOME/.rbenv" RBENV_VERSION="2.7.1" RAILS_ENV="production" 
RAILS_GROUPS="assets" ; $HOME/.rbenv/bin/rbenv exec bundle exec rake assets:precompile )

[lrphael]

No real solution? I have the same problem for 2 days. And I can't solve

[ilp416]

Same issue for me. When I run command on server it finishes successfully. I check memory and CPU and all looks fine.

    capistrano (3.16.0)
    capistrano-rails (1.6.1)
    capistrano-rvm (0.1.2)

[allanjba]

@ilp416 Did you have any luck solving yours?

[obfuscoder]

Having a similar problem with a Rails 6 app (with webpack) using capistrano 3.16 and latest cap-rails and cap-rvm. When doing the assets:precompile step, capistrano is aborting almost imediatelly without any hint on why it failed. When I am running the same command on the server inside of the release directory (~/.rvm/bin/rvm default do bundle exec rake assets:precompile), everything works without problems. Though I get a few warnings about unmet dependencies and asset size limit. echo $? returns 0.

[allanjba]

@obfuscoder for me what worked was to scale up the memory for the virtual machine. I am hosting it on Azure and they allowed me to scale the VM for very cheap. So I chose a higher memory tier and the precompiled ran properly. Later I scaled the VM back so I would still pay less monthly.

[obfuscoder]

I figured out my problem. Asset compilation requires yarn on my setup. Yarn was not installed system-wide, but made available via snap. As capistrano uses a non-interactive non-login shell, it did not pick up what was set up in bashrc and co. I worked around this by installing yarn with npm system-wide. Next problem after this was, that it did not pick up my environment variables (e.g. DATABASE_URL) so I had to go through sshd_config to allow setting them via .ssh/environment, which can be a security risk, but as I am owning that host and am the only one logging in there, that was the quick solution for me.

[sbryans]

Yep! If you --trace the deploy command, the deploy:assets:precompile stage will fail at SSHKit::Runner::ExecuteError: meaning that the prod server can't process your request correctly. nodejs and yarn should be installed on the user you deploy to. Docker simplifies the stack by abstracting much of the production configuration from the developer.
