启动MongoDB（Mac）时出现故障-代码：100

我通过自制软件安装了MongoDB，在运行mongod命令时，似乎在启动时遇到了一些问题。我已经尝试正确设置data/db目录，并查看了stackoverflow的其他一些答案，但还没有找到答案。以下是我一直得到的（对不起，我是新手）：

---

只需在系统硬盘上创建目录-

/data/db/

只需在系统硬盘上创建目录-

/data/db/

这对我有效：

sudo mongod--dbpath~/data/db
这对我有效：
sudo mongod--dbpath~/data/db
你调查了什么？找到快速搜索说明。请确保目录
/data/db
存在，并且MonoDB有权访问它。您调查了什么？找到快速搜索说明。请确保目录
