新用户无法注册，控制台出现 404 错误

支持
22

好吧，我现在不太确定了。

不过，即使禁用了 Fingerprint，我仍然在日志中看到大量错误，而且在普通模式下无法创建新用户。我可以在安全模式下创建新用户，所以也许是主题组件的问题？

在十分钟内，我收到了以下三种回溯信息各 10 次错误：

我安装的非核心插件只有 Fingerprint（现已禁用）、Staff Alias 以及 Always-Anonymous Categories Plugin 。其他启用的插件均来自核心。

我的主题组件包括：

我应该逐个关闭主题组件吗？我没有任何我认为会与登录过程产生交互的内容。

23

我完全不知道发生了什么。我禁用了每一个主题组件和插件，但仍然在 /logs 中看到相同的错误，并且匿名用户在浏览器中收到关于 /assets/detect.map、/assets/vendor.map、/assets/start-discourse.map 和 /assets/browser-update.map 的 404 错误。仍然无法创建新用户。

24

我刚刚通过 Discourse ID 成功创建了一个新帐户，没有问题。

注销后再登录也可以正常工作，没有问题。

控制台中没有错误：

你们所做的任何更改似乎都奏效了？

它响应速度也很快，这很好。

这些错误来自 sidekiq（作业调度程序），表明是某种系统级别的问题，而不是软件级别的问题。

线程数量、打开的文件数量有限制吗？内存受限了吗？你们运行了多少个 unicorn 线程？

您创建了交换文件（swapfile）吗？

您配置 MaxMind DB 下载了吗？

同样，您可以忽略这些错误，因为它们不会影响功能，只会显示在打开浏览器开发者控制台的人员面前。

25

需要注意的一个陷阱是，有些插件即使在禁用时仍然会运行一些代码。我不知道这三者是否属于这种情况，但如果你想确定哪个插件是罪魁祸首，最好的办法是将其完全从 app.yml 文件中删除并进行测试。

你也可以对主题组件做同样的事情，但正如你所指出的，它们似乎不与登录交互。

26

自从我上次创建用户以来，我在管理仪表板中没有看到任何新用户，您是删除了吗？

我只是在 1GB 的 DO (DigitalOcean) 机器上通过控制台运行了一行安装脚本，之后除了在 Discourse 设置向导/管理仪表板中进行操作外，没有做任何更改。我的机器配置是
1 GB 内存 / 25 GB 磁盘 / Ubuntu 24.04 (LTS) x64。内存使用率一直非常高，大约在 60-75%，我应该升级到内存更大的机器吗？

我只是按照 discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub 上的基本云安装说明进行操作，除了在 app.yml 中添加插件并重建之外，我什么都没有动过。

是的，当我第一次运行安装程序，并且控制台提示询问我是否要创建交换文件时，我选择了“是”。机器控制台显示交换使用率为 81%。

从 app.yml 中移除指纹识别（Fingerprint）解决了所有错误并修复了登录问题，非常感谢。
