Cannot mkdir /data/db (or sudo mkdir /data/db) for mongodb. Haven't been able to find an answer here that works

Question

I get this when I run mongod -

And then I receive a "mkdir: /data: No such file or directory" when I try to create it

尝试使用 sudo 运行，问题可能出在权限或使用此命令创建目录 sudo mkdir -p /data/db 然后重新启动 MongoDB 服务
