Rather than modifying the hardcoded url path, you'd be better looking at The Asset Pipeline Rails Guide (css and sass) and using one of the listed asset pipeline helpers. 您不必修改硬编码的URL路径，而是更好地查看“资产管道导轨指南”（css和sass）并使用其中一个列出的资产管道帮助程序。
That way, using the image-path("asset.png") syntax, your referenced asset will always be correct. 这样，使用image-path("asset.png")语法，您引用的资产将始终是正确的。

I believe you can resolve this by viewing your jquery-ui.css and/or jquery-ui.theme.css and finding the line that is pointing to and removing images at the start so therefore it would look like this. 我相信您可以通过查看jquery-ui.css和/或jquery-ui.theme.css并找到指向并在开始时删除images的行来解决此问题，因此它看起来像这样。
url(ui-bg_flat_75_ffffff_40x100.png)
instead of: 代替：
url(images/ui-bg_flat_75_ffffff_40x100.png)
Its looking at the wrong path therefore you will receive this error. 因此，它会查看错误的路径，您将收到此错误。

你能不能只改变图像的路径，或者确保它出现在你的/ public / assets / images目录中？
