部署react-rails gem时找不到服务器渲染文件

问题描述

我将rails 5.1.7与gem react-rails一起使用。

我在erb视图中添加了一个react组件：

<%= react_component("cardlist",{ all_cards: @all_cards },{prerender: true}) %>

在我的本地环境上可以正常工作，但是将应用程序部署到heroku时，如果我尝试访问包含react_component助手的erb，则会在日志中收到以下消息：

ActionView::Template::Error: Webpacker can't find server_rendering.js in /app/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.
Your manifest contains:
{
}

此刻我正在使用yarn.lock文件，但尝试使用package-lock.json时它也显示相同的消息。

我的webpacker.yml文件如下：
