ocamlfind的編譯失敗「install -m 0755 ocaml-stub

Question

我是OCaml的新手，我試圖安裝cohttp。因爲我沒有接受Xcode許可協議（OS X Sierra 10.12 0.6）我得到一個錯誤，而包管理器（OPAM）正試圖安裝一個子依賴性，ocamlfind

日誌文件是空的ENV文件有這個（編輯淡然）。

我沒有太多要去調試此任何建議從哪裏去 這裏？

爲opam這GitHub的問題使我爲我工作的解決方案：https://github.com/ocaml/opam-repository/issues/10064

到GitHub的問題的解決方案是，用戶必須在本地目錄，.，在他們$PATH而導致錯誤的install命令正在運行。這不是我的問題，但我的路上有一個額外的:。

/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 

根據下面有兩個冒號的行中的路徑字符串將添加空字符串作爲被解釋爲當前目錄路徑的一部分的註釋。

刪除多餘的冒號允許安裝ocamlfind成功。
