推荐答案

在尝试安装Mirage时，我遇到了相同的问题，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不会"cd src"，但可以"cd ./src".快速解决方案是在运行opam之前执行以下操作(或将其放入您的.bash_profile中.

I had the same problem trying to install mirage, the problem is because the current directory is not in the CDPATH by default on macOS X. The posix /bin/sh will not "cd src" though can "cd ./src". The quick fix is to do the following before running opam (or just put it in your .bash_profile.

export CDPATH=. opam install WHATEVER

export CDPATH=. opam install WHATEVER
