ocamlfind 的编译在“install -m 0755 ocaml-stub”处失败

Question

我是 OCaml 的新手，我正在尝试安装 cohttp。由于我没有接受 Xcode 许可协议 (OS X Sierra 10.12.6) 失败后，包管理器 (opam) 尝试安装子依赖项时出现错误，ocamlfind.

我没有太多可以继续调试的东西。关于从这里去哪里有什么建议吗？

opam 的这个 github 问题使我找到了一个对我有用的解决方案：https://github.com/ocaml/opam-repository/issues/10064

github 问题的解决方案是用户在他们的 $PATH 中有本地目录 .，这导致错误的 install 命令是运行。这不是我的问题，但我的路径中有一个额外的 :。

/Users/greg/.nvm/versions/node/v6.5.0/bin::/opt/chefdk/bin:/usr/local/mysql/bin:/usr/local/share/npm/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

根据下面的评论，路径字符串中连续有两个冒号会将空字符串添加为路径的一部分，该路径被解释为当前目录。

删除多余的冒号可使 ocamlfind 安装成功。
