Capistrano deployment failing on assets:precompile

Question

I have been using capistrano 3 for my rails app for sometime. Today it started failing at assets precompilation step with the following on logs that aren't very helpful:

On the server I have

1. node 10.12.0
2. yarn 1.10.1
3. rails 5.1.6
4. ruby 2.5.1
5. rbenv 1.1.1

Edit: My yarn.lock file looks like so:

# THIS IS AN AUTOGENERATED FILE. DO NOT EDIT THIS FILE DIRECTLY.
# yarn lockfile v1

Actually, I don't use yarn for anything--was putting up with it because Rails decided to use it by default. I'll be happy we can remove it forever and have the error above be gone with it.

Answer 1

Looks like you don't have yarn installed in your deployment server. Did you already installed it? If not, try this command before a new deploy:

npm install yarn -g
