ruby-on-rails - 当我运行 rails server 时,Webpacker 无法编译
问题描述
我正在启动一个新的 React-Rails 项目,并使用 rails server 和 webpack-dev-server 启动并运行示例应用程序(使用foreman start
命令运行)。
但是,现在我尝试仅使用 rails 服务器 ( bundle exec rails s
) 查看该站点,并且没有任何渲染。Webpack 没有给出任何关于编译的输出,所以看起来它只是没有运行。这是我的日志输出:
Started GET "/" for ::1 at 2020-10-08 10:31:02 -0400
Processing by HomeController#index as HTML

Everything's up-to-date. Nothing to do

ActionController::RoutingError (No route matches [GET] "/packs/js/index-73dbfbccb8bc3bfa596a.js"):
这是我的 webpacker 配置文件:

谁能帮我弄清楚为什么当我运行 rails 服务器时我的 webpack 甚至无法运行?
解决方案
事实证明,我错过了以下几行packs/application.js
:
import 'core-js/stable'
import 'regenerator-runtime/runtime'
