第一次设置 perlbrew

创建设置脚本~/.perlbrew.sh：

# Reset any environment variables that could confuse `perlbrew`:
export PERL_LOCAL_LIB_ROOT=
export PERL_MB_OPT=
export PERL_MM_OPT=

# decide where you want to install perlbrew:
export PERLBREW_ROOT=~/perlbrew
[[ -f "$PERLBREW_ROOT/etc/bashrc" ]] && source "$PERLBREW_ROOT/etc/bashrc"

创建安装脚本 install_perlbrew.sh：

source ~/.perlbrew.sh
curl -L https://install.perlbrew.pl | bash
source "$PERLBREW_ROOT/etc/bashrc"

# Decide which version you would like to install: 
version=perl-5.24.1
perlbrew install "$version"
perlbrew install-cpanm
perlbrew switch  "$version"

运行安装脚本：

./install_perlbrew.sh

添加到你的~/.bashrc 的末尾

[[ -f ~/.perlbrew.sh ]] && source ~/.perlbrew.sh

来源~/.bashrc：

source ~/.bashrc
