在主目录中安装perl模块时出现问题

Question

我们在HPC集群上安装了Perl（5.26）作为模块环境中的模块。因为我们不希望在整个集群上安装单个用户请求的所有Perl模块，所以我们要求他们在其中一个目录（home，workspace，...）中安装所需的perl模块。

我们建议使用cpanm和local :: lib来安装所需的模块。 Cpanm安装在我们的集群上，用户自己安装local :: lib。然后他们应该能够自己安装perl模块。

实际上，这适用于某些模块。首先，我们设置local :: lib并设置环境

# 1. Install local::lib in your home
wget https://cpan.metacpan.org/authors/id/H/HA/HAARG/local-lib-2.000024.tar.gz
tar xvf local-lib-2.000024.tar.gz
cd local-lib-2.000024
# Install local::lib in your home
perl Makefile.PL --bootstrap
make test && make install

# 2. Configure local::lib, because cpanm uses this configuration. Otherwise cpanm would install modules to system perl, which is not writable for normal users
echo 'eval "$(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)"' >>~/.bashrc
source ~/.bashrc;

现在我们尝试安装一个模块：

cpanm html::PullParser

它试图安装依赖HTML :: Tagset，它说安装了HTML :: Tagset，但之后找不到依赖。用户PERL5LIB目录中有一个Tagsat目录，但它是空的：

Configuring HTML-Tagset-3.20 ... OK
Building and testing HTML-Tagset-3.20 ... OK
Successfully installed HTML-Tagset-3.20
! Installing the dependencies failed: Module 'HTML::Tagset' is not
installed
! Bailing out the installation for HTML-Parser-3.72.
1 distribution installed

有人遇到过相同的行为并知道如何解决这个问题吗？对于像Math :: CDF这样的模块，它可以工作。

编辑以回答评论：

PERL5LIB因此改变了@INC：

> set | grep ^PERL
PERL5LIB=~/perl5/lib/perl5:/opt/bwhpc/common/devel/perl/5.26/lib/site_perl/5.26.1:/opt/bwhpc/common/devel/perl/5.26/lib
PERL_BIN_DIR=/opt/bwhpc/common/devel/perl/5.26/bin
PERL_HOME=/opt/bwhpc/common/devel/perl/5.26
PERL_LIB_DIR=/opt/bwhpc/common/devel/perl/5.26/lib
PERL_LOCAL_LIB_ROOT=~/perl5
PERL_MAN_DIR=/opt/bwhpc/common/devel/perl/5.26/man
PERL_MB_OPT='--install_base "~/perl5"'
PERL_MM_OPT=INSTALL_BASE=~/perl5
PERL_VERSION=5.26

> perl -I$HOME/perl5/lib/perl5 -Mlocal::lib
PERL_MB_OPT="--install_base "~/perl5""; export PERL_MB_OPT;
PERL_MM_OPT="INSTALL_BASE=~/perl5"; export PERL_MM_OPT;

使用-v输出cpanm：
