我不太明白这是怎么回事，但这看起来像是一个 bug。我试图在这个站点上执行 bootstrap 操作。没有使用任何非标准插件。我只是将资源从一个存储桶迁移到了另一个，目前一切正常。我原本打算再进行一次重建，以便将 DISCOURSE_S3_UPLOAD_BUCKET 添加到环境变量中，这样它就不会在用户界面中显示。第一次失败后，我注释掉了那一行，并尝试使用三天前还能正常工作的相同配置再次运行。

我曾怀疑是不是 CDN 的 URL 有问题，但上面所有包含该 URL 的行都运行正常。
这是否意味着他们的主题中存在有问题的 CSS？如果是的话，那可真糟糕。他们的母版主题中只包含了一些 CSS。此外还有这些组件：https://github.com/discourse/DiscoTOC.git 和 https://github.com/davidtaylorhq/discourse-loading-slider.git。
