我的配置文件-
rails: bundle exec rails server
webpack: ./node_modules/.bin/webpack-dev-server --config config/webpack.config.js
我错过了什么吗？
最佳答案
您可以尝试以下方法:
heroku 运行控制台
关于ruby-on-rails - Heroku 控制台无法启动 - 无法加载此类文件 --rack/handler/console，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43077898/
