Question

我正在使用Log4Perl模块进行日志记录。当我运行应用程序时，我在控制台上获得了一些Log4Perl模块日志：

Subroutine import redefined at C:/Strawberry/perl/site/lib/LOG/Log4perl.pm line 76.

Subroutine remove_logger redefined at      C:/Strawberry/perl/site/lib/LOG/Log4perl.pm line 602.

我不知道他们为什么要来。我也尝试了各种日志级别，但我仍然得到这些。

Log::Log4perl而非Log::Log4Perl。

From Log4perl FAQ

如果您使用的是Windows，并且收到警告消息，例如

常量子例程Log :: Log4perl :: _ INTERNAL_DEBUG重新定义于       C：/Programme/Perl/lib/constant.pm第103行。子程序导入重新定义于       C：/Programme/Perl/site/lib/Log/Log4Perl.pm第69行。子程序初始化重新定义于       C：/Programme/Perl/site/lib/Log/Log4Perl.pm第207行。

那么你可能正在使用＆＃39; Log :: Log4Perl＆＃39; （错误的大写P）而不是   正确的＆＃39; Log :: Log4perl＆＃39;。 Windows上的Perl不会处理此错误   好吧，吐出一大堆令人困惑的警告信息。但现在你   知道，只需使用正确的模块名称，你就可以了。
