Ruby on Rails: "couldn't find file 'jquery.ui.datepicker'"
提问by krstck
Okay, this is driving me nuts. I've been following the instructions to install a JQuery datepicker here: http://railscasts.com/episodes/213-calendars-revisedbut I'm getting hung up on this error:
好吧，这让我发疯。我一直在按照说明在这里安装 JQuery 日期选择器：http://railscasts.com/episodes/213-calendars-revised但我被这个错误挂了：
Sprockets::FileNotFound in Verifications#new
couldn't find file 'jquery.ui.datepicker'
(in /app/assets/stylesheets/application.css:11)
Here's application.js:
这是 application.js：
//= require jquery
//= require jquery.ui.all
//= require jquery_ujs
//= require_tree .
Here's application.css:
这是 application.css：
*= require jquery.ui.datepicker
*= require_self
*= require_tree .
and in Gemfile:
在 Gemfile 中：
group :assets do
gem 'jquery-ui-rails'
end
Anyone see what I'm missing?
有人看到我缺少什么吗？

For future readers. First, make sure you've restarted your rails server after installing the gem as krstck answered.
对于未来的读者。首先，确保在 krstck 回答安装 gem 后重新启动了 Rails 服务器。
Then, double check the version of your gem. jquery-ui-railshas changed its requiresyntax in 5.0.0. Now you should write:
然后，仔细检查您的 gem 的版本。jquery-ui-rails已更改其require语法5.0.0。现在你应该写：
//= require jquery-ui/datepicker
Also add to css
也添加到css
*= require jquery-ui/datepicker

Answering my own question here in case someone else makes the same dumb mistake. I restarted the rails server, and then it worked.
在这里回答我自己的问题，以防其他人犯同样的愚蠢错误。我重新启动了 rails 服务器，然后它工作了。

For Rails 5 users, to use the jQuerydatepicker you must add this to your application.js:
对于 Rails 5 用户，要使用jQuery日期选择器，您必须将其添加到您的application.js：
//= require jquery-ui/widgets/datepicker
And this to your application.css:
这给你的application.css：
/*
*= require jquery-ui/datepicker
*/
You can also just use the usual gem version:
您也可以只使用通常的 gem 版本：
gem 'jquery-ui-rails'
Restart your server as well.
也重启你的服务器。

adds 'jquery-ui-rails' on your Gemfile, and use a hyphen instead of a point to require jquery-ui
在您的 Gemfile 上添加“jquery-ui-rails”，并使用连字符而不是点来要求 jquery-ui
//= require jquery-ui
or downgrade the jquery-ui gem version
或者降级 jquery-ui gem 版本
gem 'jquery-ui-rails', '~> 4.2.1'
回答by Kris Quigley
Downgrading from jquery-ui-rails 5.0.0 to 4.2.1 fixed it for me.
从 jquery-ui-rails 5.0.0 降级到 4.2.1 为我修复了它。

Just to add to this: I had the same issue, I finally solved it by placing //= require turbolinksbefore the jquery requirements in application.js:
补充一点：我遇到了同样的问题，我最终通过将其放在//= require turbolinksjquery 要求之前解决了这个问题application.js：
//= require turbolinks
//= require jquery
//= require jquery.ui.datepicker
//= require jquery_ujs
//= require_tree .
