Rake multisite:migrate 已损坏

贡献 错误

今天早些时候，我在此背景下创建了一个支持主题，但我不太确定，所以我又进行了一些尝试和调查。看起来这里存在严重问题：多站点重建失败，并报错如下：

FAILED

Pups::ExecError: cd /var/www/discourse && sudo -E -u discourse bundle exec rake multisite:migrate failed with return #<Process::Status: pid 5780 exit 1>

** FAILED TO BOOTSTRAP ** 请向上滚动并查找更早的错误消息，可能不止一条。
./discourse-doctor 可能有助于诊断问题。

在现有站点的 web_only 容器内尝试运行 rake multisite:migrate 时，出现以下错误：

root@discourse-web-only:/var/www/discourse# rake multisite:migrate
Multisite migrator is running using 20 threads

这是相同的错误，报告 ID 为 -6 的上传记录缺失。我在至少 3 个不同提供商的测试实例上遇到了此问题，因此我很有信心认为这是一个 bug。如果我错了，请纠正我。

我暂时正在针对 latest-release 构建多站点 Discourse，这使我能够成功启动。看来问题出在 2.5.0 beta 7 发布之后的某个提交中。

我刚刚重建了几个实例，一切看起来都没问题。问题已修复，此话题可以关闭了 :slight_smile:
