对于全新的Rails 6应用，在开发模式下将root to: "home#index"添加到我的路线后，我得到以下信息：
这基本上意味着Rails 6 不再需要工作
，如果您需要自定义的根路由。Webpacker::Manifest::MissingEntryError in Home#index Webpacker can't find application in /home/mark/testapp/public/packs/manifest.json. Possible causes: 1. You want to set webpacker.yml value of compile to true for your environment unless you are using the `webpack -w` or the webpack-dev-server. 2. webpack has not yet re-run to reflect updates. 3. You have misconfigured Webpacker's config/webpacker.yml file. 4. Your webpack configuration is not creating a manifest.

rails assets:precompile，但返回了error Command "webpack" not found.。然后，我尝试在compile中将false设置为webpacker.yml以及手动创建public/packs/，但似乎无济于事。
谢谢！
对于一个全新的Rails 6应用程序，在开发模式中将root添加到：“ home＃index”到我的路由后，我得到以下信息：这基本上意味着，如果您需要自定义，Rails 6将不再起作用...
我以前有这个问题。这就是我的解决方法，希望对您有所帮助。
