Ruby on rails 无法在本地生产环境中启动rails-rails 5

这是我第一次在生产环境中启动rails应用程序。我首先运行了

railsserver-e产品

，然后必须获得密钥。之后，我运行了这一行

bundle exec rake assets:precompile db:migrate RAILS\u ENV=production

。当我运行这一行时，我又运行了一次

rails server-e production

，在我的终端中出现了以下错误（参见最后4行）以及浏览器中的404错误页面：

krav@krav-Q534UXK:~/Desktop/cnd$ rails server -e production

当我转到此处给出错误的行时，它们分别是：

第20行

<%= image_tag "AdobeStock_95578405.jpeg" ,alt: "slidebg1", :data => {bgposition: "center bottom"} , :data => {bgrepeat: "no-repeat"} ,:data => {bgfit: "cover"} , :class => "rev-slidebg" %>

{bgposition:“中间-底部”}，：data=>{bgpeat:“无重复”}，：data=>{bgfit:“cover”}，：class=>“rev slidebg”%>

第107行

<%= image_tag "AdobeStock_108067927.jpeg" ,alt: "slidebg1", :data => {bgposition: "center bottom"} , :data => {bgrepeat: "no-repeat"} ,:data => {bgfit: "cover"} , :class => "rev-slidebg" %>

{bgposition:“中间-底部”}，：data=>{bgpeat:“无重复”}，：data=>{bgfit:“cover”}，：class=>“rev slidebg”%>

在开发中，这很好。我不明白为什么这些行给了我一个错误，不允许web应用程序启动它们看起来是正确的，让我在开发模式中获得了所需的外观

行中有重复的数据键，并且只能有一个：

i、 e.这：

{bgposition:“中间-底部”}，：data=>{bgprepeat:“无重复”}，：data=>{bgfit:“cover”}，：class=>“rev slidebg”%>

应该是这样：

{bgposition:“中间底部”，bgpeat:“无重复”，bgfit:“封面”}，：class=>“rev slidebg”%>
