【问题描述】：

我有一个图像标签来显示我的头像。当我将它部署到 aws beanstalk 时，该标签在开发模式下工作，但不在生产模式下工作。我查看头像图片的位置显示为“img 0645”，这几乎就像图像已保存但以某种方式或 id 显示 img 名称一样。图片本身不显示！！怎么让图片显示？？？谢谢！！！

我正在使用

Postgres、puma、aws beanstalk、ruby on rails

不确定这是否有帮助，但我使用 Find 在日志中查找带有头像的任何内容，并想出了这些。

【参考方案1】：

尝试将此添加到您的config/environments/production.rb

config.serve_static_assets = false

嘿大卫！我尝试了您的代码并重新部署，然后重新启动了服务器。但还是没有用。 production.rb 文件中的另一个配置是否与该语句冲突？？

@MichaelLombardo 你确实有另一行在你的production.rb - config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present? 中设置这个变量。您可以尝试将其注释掉。根本问题可能是让 nginx 为您提供静态文件，而不是默认的 rails 服务器，所以如果问题不在这里，可能是您的 ngnix 设置。

我不太确定如何设置 ngnix！我只创建了一个名为 .ebextensions 的文件夹，并添加了一个名为 01_files.config 的文件，但我无法着手增加 file_body_size。我试着把它注释掉，但它没有工作：/必须是 nginx 设置..我只是不知道怎么做。

这里有很多可以尝试的东西forums.aws.amazon.com/thread.jspa?threadID=150904

我更改了 config.serve_static_assets = true.. 我现在可以看到图片但是当我在浏览器中检查代码时，它似乎没有保存到 s3，而是保存在我的 rails 应用程序的公共文件夹中不好！我开始考虑迁移到heroku，直到aws修复了这个服务！！！ :)。我真的不知道如何访问 ngnix 文件以查看里面有什么或在哪里可以找到它们。不确定我是在 aws 服务站点还是在我的 rails 应用程序中找到它们。我知道您通过应用程序为您的服务器设置命令，但我不知道如何查看 beanstalk 中的更改。或在beantalk中访问它们以查看！
