Perhaps someone will present a better answer. This is how I fixed it.

也许有人会提出更好的答案。这是我修复它的方式。

I got rid of the gem. Downloaded the javascript and css files from the datatables website:

我摆脱了宝石。从datatables网站下载了javascript和css文件：

jquery.dataTables.min.css
jquery.dataTables.min.css
jquery.dataTables.min.js
jquery.dataTables.min.js

Put these files in vendor/assets/stylesheets and vendor/assets/javascripts respectively.

将这些文件分别放在vendor / assets / stylesheets和vendor / assets / javascripts中。

I downloaded the missing images from here and stuck them in my vendor/assets/images folder that I created.

我从这里下载了丢失的图像并将它们粘贴在我创建的vendor / assets / images文件夹中。

I did a replace all on the text in jquery.dataTables.min.css and replaced "/images/" with "/assets/"

我在jquery.dataTables.min.css中对文本进行了全部替换，并将“/ images /”替换为“/ assets /”

And that fixed it. Hope this helps someone.

并修复了它。希望这有助于某人。

I had the same problem and fixed it using a different version of the jquery.dataTables.min.css file, where the images are written as strings rather than as references to a file.

我有同样的问题并使用不同版本的jquery.dataTables.min.css文件修复它，其中图像被写为字符串而不是文件的引用。
