macos - Frama-c安装-配置：错误：找不到ocamlfind

当我尝试在 mac 上启动 Frama-C 并运行 ./configure 命令时。它说它找不到ocamlfind。但我已经安装了它。

xhy0908deMacBook-Pro:frama-c-Phosphorus-20170501 xhy0908$ opam install ocamlfind
[NOTE] Package ocamlfind is already installed (current version is 1.7.3).

我不知道是什么问题......

Answer 1

如果您使用的是 OPAM，则需要使用

eval `opam config env`

或者，正如@glennsl 建议的那样，另一种语法，

eval $(opam config env)

此命令将设置 PATH 变量，使其ocamlfind可见。
