Question

我是Jenkins和Perl的新手，我正在尝试使用Jenkin Job安装Log4perl模块。下面是我在Jenkin的执行shell框中使用的命令

perl -MCPAN -e 'install Log::Log4Perl'

以下是Jenkin控制台日志消息

12:44:49 PATH="/home/jenkins/perl5/bin${PATH:+:${PATH}}"; export PATH;
12:44:49 PERL5LIB="/home/jenkins/perl5/lib/perl5${PERL5LIB:+:${PERL5LIB}}";    export PERL5LIB;

在日志消息中显示

警告：无法安装Log :: Log4Perl，不知道它是什么。

我不确定是否应该忽略上述陈述。另外如何确认log4perl模块是否已成功安装。

您不应该依赖于在Perl中省略字符串周围的引号。 perl -MCPAN -e 'install Log::Log4Perl'最好写成perl -MCPAN -e 'install "Log::Log4Perl"'（如果您尝试安装/更新CPAN本身加载的任何模块，则省略引号也会导致奇怪的问题。）
无论如何，整个事情可以简化为cpan Log::Log4Perl。
发生错误是因为Log::Log4Perl确实不存在，但Log::Log4perl确实存在（小写p）。

因此：cpan Log::Log4perl应该做你想做的事。

至于你的其他问题：“无法安装......”意味着安装失败（这不是你可以忽略的）。

要确认该模块是否存在，请尝试加载它：perl -e 'require Log::Log4perl'（如果它不存在，您将获得Can't locate Log/Log4perl.pm in @INC ...）。
