Reactjs 在heroku上部署React Redux网页包

嗯，我有一个大问题，我有一个前端只响应发送请求到RubyonRails api，我们使用redux，babel和webpack。我的问题是，我不能让这个项目在Heroku上运行

这是来自heroku的503响应错误

感谢您的帮助。

heroku的默认配置是将依赖项缓存在

节点\u模块中，并将生产环境设置为true

缓存
node_模块
可防止安装其他模块。
生产环境阻止安装
package.json
中的
devdependency


另外，webpack dev server在Heroku中不起作用，因此最好创建一个小型web服务器（我个人喜欢Express server），为
dist
文件夹提供服务，然后部署应用程序

此外，如果您仍然面临问题，请尝试运行heroku logs--tail

并将日志粘贴到此处。

我的看法是，应该在依赖项下重新安装依赖项。在类似的情况下，我尝试在Heroku上部署时出现了错误屏幕。devdependency将被忽略，并且每当您的代码要求它们时，就会发出警报

我想我也有同样的问题。你找到解决办法了吗？没有，我没有找到
