rails on heroku : webpack dev_server configuration not found

Question

I have a rails project deployed to heroku. After deployment, the CSS packaged by webpack does not work, but it works normally local. Famous in Heroku's Application Logs: webpack dev_server configuration not found in /app/config/webpacker.yml[production] Please run bundle exec rails webpacker:install Webpacker I execute $ heroku run bundle exec rails webpacker:install，the situation remains unchanged. I think the problem is that webpack is not working properly on heroku, but I don’t know how to deal with it. Please give me some advice, thanks
