以下是磁盘上的文件（以其中一张图片为例）——注意那个 0 KB 的 10x10 png 文件：

好的，那么问题出在哪里？直接忽略那些格式错误的图片，继续操作吧。

（或者把它们从它们所在的帖子中编辑掉？）

这些图片并非格式错误，它们在帖子中显示正常。

格式有问题（或者更准确地说，是未生成）的是“快速滚动”的优化图片，它无法从原始图片生成。

在快速滚动浏览帖子时，可以检测到该图片缺失。

我已修改标题以提高清晰度。

你好，@md-misko
你的问题解决了吗？
我也遇到了类似的问题。

我之后已迁移到 S3，无法再对 S3 运行 rake uploads:missing 命令，但我已检查上述引用的那个文件，它在 S3 上的大小现在不为 0，所以看来这个问题已经修复了。

你使用的是最新版本吗？

哦！我不知道这个命令不适用于 S3 存储桶。

是的。我总是会升级到最新版本。最多可能滞后 2-3 天。

无论如何，如果你恰好知道，查找缺失上传图像的最佳命令是什么？或者，如果路径因某种原因损坏，将帖子 URL 映射到正确存储桶中正确图像的命令是什么？

这似乎与原始帖子中描述的问题无关。或许您可以在 Support 中开启一个新主题，并详细描述您遇到的具体问题。
