我正在尝试使用生成的Xcode工作区的Unreal源代码构建我的UnrealEngine项目。然而，Xcode或xcodebuild只是在构建过程开始后不久挂起。我在系统日志、构建日志中找不到任何有用的信息，也找不到为什么会挂起。不需要很长时间，我的CPU几乎空闲了。
有人碰到这个问题了吗？我已经两个多月没有在虚幻论坛上收到关于这个话题的回复了。

我也遇到过类似的问题，不能肯定你也遇到了同样的问题。但问题是/bin/ps -eaw -o pid,comm可能产生超过64K的输出数据。运行/bin/ps -eaw -o pid,comm | wc查看情况是否如此。
这听起来可能很牵强，但在类MacBuildHostPlatform和方法GetProcesses()中的BuildHostPlatorm.cs内部，会使用以下命令进行进程调用：
Proc.Start();
Proc.WaitForExit();
// ... then output is read
因此，如果输出大于管道缓冲区，命令就会被卡住。这已在4.27中通过移动Proc.WaitForExit()直到读取该过程的输出来解决。如果使用的是早期版本，只需将WaitForExit();移到读取循环的正后方即可。
