perl - cpanm 不安装模块

Question

我是一个全新的 perl 用户，正在尝试安装 perl 模块及其依赖项。

我正在尝试在新的 Ubuntu 16.10 云服务器实例上安装我需要的 perl 依赖项，但它们没有注册为已安装。

例如

cpanm --skip-installed LWP::Simple

我是否使用了正确的工具？在哪里可以找到或生成更详细的错误日志？

以下是我的安装过程中的选择，但实验可能意味着它并不完全具有代表性。

sudo apt-get install unzip make cmake perl build-essential curl cpanminus
cpanm --self-upgrade --sudo
sudo ln -s /usr/bin/unzip /bin/unzip
export PERL_INSTALL_ROOT=/home/ubuntu/perl5
export PERL5LIB=/home/ubuntu/perl5
export PERL_CPANM_OPT="--local-lib=/home/ubuntu/perl5"
mkdir -p /home/ubuntu/perl5
chown -R ubuntu:ubuntu /home/ubuntu/perl5
chown -R ubuntu:ubuntu /home/ubuntu/.cpanm
cpanm --local-lib=/home/ubuntu/perl5 local::lib && eval $(perl -I /home/ubuntu/perl5/lib/perl5/ -Mlocal::lib)
cpanm File::Copy::Recursive
cpanm Archive::Zip
cpanm --skip-installed LWP::Simple

在新的服务器上这个过程有效

sudo apt-get update
sudo apt-get install unzip make cmake perl build-essential curl cpanminus
echo $?
sudo ln -s /usr/bin/unzip /bin/unzip
mkdir -p /home/ubuntu/perl5
chown -R ubuntu:ubuntu /home/ubuntu/perl5
cpanm --local-lib=/home/ubuntu/perl5 local::lib && eval $(perl -I /home/ubuntu/perl5/lib/perl5/ -Mlocal::lib)
echo "cpanm --local-lib=/home/ubuntu/perl5 local::lib && eval $(perl -I /home/ubuntu/perl5/lib/perl5/ -Mlocal::lib)" >> /home/ubuntu/.bashrc
cpanm File::Copy::Recursive
cpanm --skip-installed LWP::Simple
echo $?
