我不知道它是否在Catalyst内工作，但是通常您可以通过包括CPAN模块来强制堆栈跟踪。 Carp :: Always ，例如通过在程序中的某个地方写入使用Carp :: Always; 或者使用启动perl脚本-MCarp :: Always 开关。

I am not sure if it works within Catalyst, but usually you can force a stacktrace by including the CPAN module Carp::Always, e.g. by writing somewhere in your program use Carp::Always; or starting the perl script with the -MCarp::Always switch.
