I am following a tutorial on setting up MongoDB on my system. When I try to make a directory by using a command as under:
sudo mkdir /data/db
inside of /usr/local/ bin, I get the following error:
mkdir: /data: No such file or directory
However this was possible on the older version of Mac OS I had. How should I go about solving this issue? Kindly help.

On Catalina you do not have r/w to the "/"
How about
~/data/db

Okay found it. Typing
db.serverCmdLineOpts()
in the mongo shell tells where the mongodb data is being stored as set by homebrew. Read the following article for this
https://stackoverflow.com/questions/13827915/location-of-the-mongodb-database-on-mac/18938940
So I used homebrew to install mongodb on my system following the article
https://zellwk.com/blog/install-mongodb/.
However, calling the
mongod --datapath=/System/Volumes/Data/data/db
hangs the process at a certain point. And so the new data/db path is not being set , therfore calling
mongod
does not start the mongodb as it shuts down because that data/db does not exist for it.
But starting the service using the brew command
brew services mongodb-community
starts it then calling
mongo
starts the shell.
Why is this happening?
Does brew create a /data/db somewhere?
Thanks! But what does
~
represent?
Thank you! While looking through the links you have shared, I found an article to be very useful:

~ is your home directory.
macOS Catalina runs in a dedicated, read-only system volume
Since the directory /data/db is coded as MongoDB default, a workaround is to specify a different dbpath that is not located on the root directory.
For example:
mongod --dbpath ~/data/db
This will place MongoDB's data in your home directory. Just make sure that the path ~/data/dbactually exists.
