Ruby on rails 样式表或JavaScript文件的Rails 404错误

Rails无法在生产环境中加载（404错误）CSS&JS文件，但在开发环境中加载它们没有问题

我使用Capistrano进行部署并运行Rails 3。我的发展道路是/www/myapp，但我的生产道路是/www/myapp/current

应用程序本身似乎工作正常，因此问题似乎与CSS/JS文件无关

我尝试在环境/production.rb中将RAILS\u ROOT变量设置为/www/myapp/current，但没有任何区别，文件仍然无法加载

以下是生产日志中的完整堆栈：

错误消息看起来您的Rails应用程序正在获取对静态文件的请求。Rails3默认情况下不提供静态文件，因为Web服务器可以做得更好。您应该检查Web服务器的配置。如果请求的公共目录中存在静态文件，则应将其配置为首先查看，如果没有静态文件，则仅将请求转发给Rails应用程序

---

或者，您也可以在config/environments/production.rb中使用

config.service\u static\u assets=true

启用Rails来服务静态文件。但是，在生产环境中不建议这样做，因为您确实不应该仅仅为了服务静态文件而浪费Rails应用程序的处理资源。最好告诉Web服务器这样做。

我通过运行以下命令修复了此问题：

RAILS_ENV=production rake assets:precompile

我的环境是

Nginx

+

Unicorn

+

Rails4

我完全忘记了这一点。谢谢你指出这一点。我将nginx配置为查找unicorn，现在它可以完美地工作了。谢谢
