新用户，我一直没有构建测试，所以我是个白痴。

应用程序正在运行，但测试失败。以下是似乎相关的内容：

...

【解决方案1】：

Rake 未能报告其运行测试的子进程被信号杀死的事实。

rake aborted! Command failed with status ():

注意 () 之间缺少的退出代码。您可以通过运行“strace -o rake.strace rake”来发现信号，并在结果文件的末尾附近查看类似的内容

[{WIFSIGNALED(s) && WTERMSIG(s) == SIGVTALRM}], 0, NULL)

在我的情况下，这是（现在可能是臭名昭著的）mysql 2.8.1 gem 在 ruby-1.8.6 的较新补丁级别下运行时失败并出现“虚拟计时器已过期”（-p399 已损坏，不确定哪个较旧版本仍然有效）。

[哎呀，忘记修复了]

接下来的步骤...

在 rake 之外或在 strace 下运行该进程，以找出信号是什么
假设是 mysql 2.8.1 / Ruby 1.8.6-p399 问题并降级到 mysql '~>2.7.0' 或更早的 Ruby 1.8.6 补丁级别，或者升级到 Ruby 1.8.7
