Question

我在Mac OS X 10.10上安装了带自制程序的opam。但我无法使用opam安装任何东西。这是我尝试安装ocamlfind时获得的示例错误输出：

Answer 1

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

更新

有时，使用Illegal Instruction，自酿的opam会失败，在这种情况下，您需要从源代码重新安装opam：

brew reinstall --build-from-source opam

此外，您还需要一个有效的工具链，即编译器，自动工具和其他开发人员工具。您可以尝试使用brew安装它，例如brew install autotools等。或者您可以尝试安装xcode工具链，包括Apple命令行开发人员工具。

Answer 2

我在尝试安装海市蜃楼遇到同样的问题，问题是因为当前目录默认情况下不在MacOS X上的CDPATH.posix / bin / sh不会“cd src”虽然可以“cd ./src ”。快速修复是在运行opam之前执行以下操作（或者只是将其放在.bash_profile中。

export CDPATH=. opam install WHATEVER

无法使用opam安装任何东西
