ocamlfind的编译失败“install -m 0755 ocaml-stub

Question

我是OCaml的新手，我试图安装cohttp。因为我没有接受Xcode许可协议（OS X Sierra 10.12 0.6）我得到一个错误，而包管理器（OPAM）正试图安装一个子依赖性，ocamlfind

日志文件是空的ENV文件有这个（编辑淡然）。

我没有太多要去调试此任何建议从哪里去 这里？

为opam这GitHub的问题使我为我工作的解决方案：https://github.com/ocaml/opam-repository/issues/10064

到GitHub的问题的解决方案是，用户必须在本地目录，.，在他们$PATH而导致错误的install命令正在运行。这不是我的问题，但我的路上有一个额外的:。

/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 

根据下面有两个冒号的行中的路径字符串将添加空字符串作为被解释为当前目录路径的一部分的注释。

删除多余的冒号允许安装ocamlfind成功。
