Mastodon: WebPack compilation failed : process out of memory

[joachimesque]

I'm not using Docker.

Here's the message I got when updating my instance earlier today:

~/live$ RAILS_ENV=production bundle exec rails assets:precompile

Compiling…
Compilation failed:



#
# Fatal error in , line 0
# API fatal error handler returned after process out of memory
#

How can I relaunch the compilation? When I retried the command, all I got was:

~/live$ RAILS_ENV=production bundle exec rails assets:precompile

And now after restarting the service for my instance, the website displays nothing, and the console only has this message:

Error: Reducer "custom_emojis" returned undefined when handling "STORE_HYDRATE" action. To ignore an action, you must explicitly return the previous state.

You can do assets:clobber. I also think there is a --force flag although I'm not sure.

Thanks! I tried assets:clobber then assets:recompile worked. I'll remember that for next time :)
