虽然这适用于 debian，但 alpine 拒绝编译 ( perl 5.20.3 && plenv)。

已安装模块 =>

apk update && apk upgrade
apk add bash wget curl perl make g++ libev-dev patch git openssl-dev openssl

如何解释 cpanm 日志中的相关错误？

所以musl-libc哪个在 alpine linux 中使用而不是 glibc，没有实现__register_atfork哪个是the linux standard base

如果你绝对确定你可以在没有非工作分叉检测的情况下生活，你可以EV通过指示它跳过该功能来安装，

export EV_EXTRA_DEFS="-DEV_NO_ATFORK"
cpanm EV
