我正在尝试安装camlzip(一个安装在opam中的OCaml软件包),但是当我运行时,opam install camlzip我得到了这个:

=> This package relies on external (system) dependencies that may be missing. `opam depext camlzip.1.05' may help you find the correct installation for your system.

现在我认为很明显它并没有实际上缺少依赖项,但我仍然可以建议命令,它说我没有遗漏任何依赖项.

可能问题在于zlibstubs.c文件,但我不确定发生了什么.

任何人都可以解雇我吗？

TL; DR

opam install depext
opam depext camlzip

说明

该opam install depext命令将安装一个opam能够安装外部依赖项的插件.它将depext向opam工具添加命令.

在opam depext camlzip将安装外部依赖,使用系统包管理器.如果不支持包管理器,则命令将失败.在这种情况下,你可以使用

opam list --external --required-by=camlzip

获取camlzip包维护者已知的所有发行版和包管理系统的所有外部依赖项.根据此信息,您可以推断出您的分发包的名称.一旦成功,将这些信息反馈给维护者也是一个好主意.
