Question

我将我的应用程序安装到Ubuntu VPS。我跟踪了“向VPS部署”的轨迹。

Everything went smooth, up until I added the following gem: https://github.com/marceldegraaf/sisow

在我的地方开发机器上,它的工作就像一个魅力, 但在我把它放到生产环境之后, 铁路应用程序将不再启动(500 内部服务器错误) 。

我尝试过一些"tweaks" 在我的独角兽配置, 部署.rb 和一堆其他的文件, 但似乎没有什么工作。

奇怪的是,当我使用:

RAILS_ENV=production bundle exec rails c

我可以使用宝石没有任何问题(? )

Answer 1

我也有同样的问题重新开始独角兽服务

/etc/init.d/unicorn_my_app stop
/etc/init.d/unicorn_my_app start

信用额度为:。

Answer 2

我也有同样的问题(尽管与不同的宝石不同 ) 。我尝试了许多事情,但最终帮助我的是重新安装红宝石(通过 rbenv ), 清理宝石,从服务器上移除应用程序, 添加到独角兽身上:

before_exec do |server| 
  ENV["BUNDLE_GEMFILE"] = "/path/to/app/current/Gemfile" 
end

并且从头开始重新部署(deply:setup)。

我不百分之百确定解决办法(最后还是一团糟), 但我希望它也能帮助你。
