perl - 命令 "cpan reports"到底是做什么的？

Question

我尝试使用命令 cpan install Moose 在 perl 5.32.0 中安装 Moose。安装失败，并显示以下消息:

Result: FAIL
Failed 448/478 test programs. 12/30 subtests failed.
Makefile:2047: recipe for target 'test_dynamic' failed
make: *** [test_dynamic] Error 255
  ETHER/Moose-2.2013.tar.gz
13 dependencies missing (Class::Load,Class::Load::XS,Data::OptList,Devel::OverloadInfo,Dist::CheckConflicts,Module::Runtime::Conflicts,Package::DeprecationManager,Package::Stash,Package::Stash::XS,Params::Util,Sub::Exporter,Sub::Identify,Test::CleanNamespaces); additionally test harness failed
  /usr/bin/make test -- NOT OK
//hint// to see the cpan-testers results for installing this module, try:
  reports ETHER/Moose-2.2013.tar.gz

我尝试了命令cpan reports ETHER/Moose-2.2013.tar.gz，并且以某种方式正确安装了Moose。这里发生了什么？ cpan reports 到底有什么作用？这与 App::cpanreports 相同吗？

那里的错误消息指的是您可以在 CPAN.pm shell 中执行的操作，而 cpan 命令没有任何内容可以映射到该操作。即使这样做了，看起来也不会一样。

不带参数的

cpan 会将您带入 CPAN.pm shell，您可以在其中发出命令(例如 install 等)。对于报告，您需要先安装LWP和CPAN::Reporter:

% cpan LWP CPAN::Reporter
...
% cpan
cpan[1]> reports ETHER/Moose-2.2013.tar.gz
Distribution: E/ET/ETHER/Moose-2.2013.tar.gz

但是，查看 CPAN Testers 可能更容易查看特定模块的结果。
