我正在尝试使用 osx 玩 mongodb，为此我需要在我的 mongodb exe 目录中使用以下内容创建一个目录
mkdir /data/db
但是，当我尝试这样做时，我的命令提示符返回以下内容
$ mkdir /data/db
mkdir: /data: No such file or directory
目前我的 mongodb exe 没有启用命令行，也就是说它不在 bash 的路径中，有谁知道如何使 mongodb 程序全局化？
提前致谢
添加所以我尝试添加 bash 文件，和
$ sudo mkdir -p /data/db/
$ mkdir -p /data/db
只需键入
$ mongod
仍然不起作用，我必须输入以下内容
$ ./mongod
但它给出了以下内容
$ ./mongod
./mongod --help for help and startup options
