我正在尝试将用户的旧帐户合并到当前的主帐户中。
他有两个之前的帐户。一个是较小的（几百个帖子），另一个有超过一千个帖子。
通过 Web 界面尝试过，即使花费了一些时间，第一个也成功了。
第二个帐户在“更改帖子所有权”状态下挂了 24 小时，我重启了两次。
所以我尝试直接使用 rake 命令，这是带有 `--trace` 的输出：
```plaintext
rake users:merge['user-source','user-target'] --trace
** Invoke users:merge (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute users:merge
rake aborted!
