我正在使用Getopt::Long::Subcommand来解析命令行参数。
但我发现在一些Perl版本中。此模块的行为不正确。
例如，如果我运行./ViewBS BisNonConvRate --sample bis_WT.tab.gz,WT。我期望输出如下：
Subcommand: BisNonConvRate
Sample list: bis_WT.tab.gz,WT
在perl-v5.18.2中，它工作正常。我得到了我预期的输出。但是在perl-v5.24.1中，它没有。我得到的输出如下：
Subcommand: BisNonConvRate
Sample list:
我检查了Getopt::Long::Subcommand的版本。它们都是相同的版本（0.102）。
有人可以帮忙解决这个问题吗？提前致谢。
以下是我配置perl环境的方法：
perlbrew install perl==5.24.1 ## or perl==5.18.2
perlbrew use perl-5.24.1
perlbrew install-cpanm
cpanm Getopt::Long::Subcommand
cpanm Bio::DB::HTS::Tabix
cpanm Bio::SeqIO
这是我在'ViewBS'中使用Getopt::Long::Subcommand的代码：

Getopt :: Long ::子命令依赖于Getopt :: Long。 Getopt :: Long ::子命令或您的特定需求与Getopt :: Long 2.43（包括）与2.50（不包括）不兼容。
简单的解决方案是升级到最新版本的Getopt :: Long。
我提交了一个ticket请求添加对Getopt :: Long 2.50的依赖。
