Mastodon: WebPacker compilation failed

[Daegalus]

I am following the Docker instructions and I keep hitting this problem, no matter how many times I restart the process. I even did the standalone setup too, and that failed at this exact problem. Standalone was run with RAILS_ENV=production. This is on a fresh install. Am I missing some steps?

@Daegalus I usually see this if you run out of memory during the build process (how much ram does your machine have?)

If it is a RAM issue, you can get around it by creating a swapfile on disk:

sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

See this blog post for a better explanation on the swapfile

@astronaut-wannabe Thanks for the tip, that actually helped me in my installation process.

I'm seeing this issue on a machine with 22GB RAM free. Not sure why this is happening.
