我在尝试将我的create-react-app部署到Heroku时遇到了麻烦。我以前工作得很好，我之前构建的页面仍然有效。但是，我构建的新页面返回以下错误：500内部服务器错误nginx。我构建的一个页面是一个只有文本的测试页面，我仍然会收到此错误。一切都在发展中很好。
我使用了create-react-app和这个构建包：https://github.com/mars/create-react-app-buildpack.git
我正在运行一个rails 5 api，只在后端作为一个单独的应用程序。
在下面构建日志和heroku日志。还包括cors.rb文件。
谢谢！
这是构建日志

Cors.rb文件在rails 5 api中只有应用程序我也在heroku中运行。
Rails.application.config.middleware.insert_before 0, Rack::Cors do
allow do
origins 'https://app-<username>.c9users.io:8082'
resource '*',
headers: :any,
methods: [:get, :post, :put, :patch, :delete, :options, :head]
end
allow do

resource '*',

end
end
答案 0 :(得分：0)
我弄清楚了，看到我在create-react-app-buildpack上打开的这个问题：https://github.com/mars/create-react-app-buildpack/issues/44
长话短说，你需要添加一个static.json文件，你不能发表评论
