我在 Mac OS X 10.10 上用自制软件安装了 opam。但我无法使用 opam 安装任何东西。这是我尝试安装 ocamlfind 时得到的示例错误输出：

brew install opam
opam init --comp=4.02.1
eval `opam config env`
ocaml

更新：

有时 brewed opam 可能会失败Illegal Instruction，在这种情况下，您需要从源重新安装 opam：

brew reinstall --build-from-source opam

此外，您还需要一个工作工具链，即编译器、自动工具和其他开发工具。您可以尝试使用brew，例如，brew install autotools等安装它。或者您可以尝试安装xcode工具链，包括苹果命令行开发人员工具。

我在尝试安装 mirage 时遇到了同样的问题，问题是因为在 macOS X 上默认情况下当前目录不在 CDPATH 中。posix /bin/sh 虽然可以“cd ./src”，但不会“cd src”。快速修复是在运行 opam 之前执行以下操作（或者只是将它放在您的 .bash_profile 中。

export CDPATH=. opam install WHATEVER
