For sass configuration of vuetify, I refer to here: https://github.com/Rails/WebPacker/Issues/2235#IssueComment-524527397
Vuetify is work ( a - la - carte setup )

All this works on my mac, but when I deploy it, I always fail with the following message:

Tasks: TOP => deploy:assets:precompile
(See full trace by running task with --trace)
The deploy has failed with an error: Exception while executing as deploy@3360.hongliang.fun: rake exit status: 1

I google search for a long time, still did not solve. Stranger to webpack, does anyone know the solution?

Try this: #2003 (comment)

Resolved, the reason for node version. Although my ubuntu server used nvm to set the node version to 12.13, in fact, the node version printed out during deployment was 6.7. This is exactly the problem. I sanctioned nvm and all node versions and manually installed the latest node.
