如何解决当使用带有react-rails gem的组件时,没有这样的文件或目录@ rb_sysopen
我将rails 5.1.7与gem react-rails一起使用。
<%= 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 (No such file or directory @ rb_sysopen - /app/public/packs/js/server_rendering-7bdf65f03078e0e44c86.js
我也尝试过添加一个App组件并渲染它,但是它始终发出相同的消息。
我还在heroku上添加了一个节点buildpack,并确保该应用仅使用npm而不是yarn,并添加了节点版本:
"engines": {
"node": "12.18.3"
}
但是我总是收到相同的消息
ActionView::Template::Error (No such file or directory @ rb_sysopen - /app/public/packs/js/server_rendering-7bdf65f03078e0e44c86.js
如果将pre render设置为true,则该组件将在生产中出现,日志上没有错误,但是我需要通过服务器渲染来完成。
按照Justing的建议,删除public / packs中的文件并在生产环境中进行编译后,我得到了:

解决方法
在我的本地环境下工作正常
您是否尝试过在本地进行预编译?
RAILS_ENV=production NODE_ENV=production rake assets:precompile
然后使用
运行您的rails应用程序RAILS_ENV=production rails s
该错误应该非常明显。我的猜测是,在预编译期间会出现一些错误,因此文件js/server_rendering-7bdf65f03078e0e44c86.js
不存在。
您可能还想确保/ public / packs目录中没有任何文件签入git repo。
