'zsh: command not found: mongo

I'm following the official instructions found here (on Mac OS Big Sur): https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/

When attempting to run mongo, I receive:

zsh: command not found: mongo

I then check if MongoDB is running by running:

brew services start [email protected]

I then receive:

Service [email protected] already started, use brew services restart [email protected] to restart

Because of this, I know MongoDB is running. What gives? I followed the official instructions from MongoDB's website.

For Apple M1 Processor:

If you install mongodb through Homebrew, follow the steps below:

  1. Open up your Terminal

  2. Type brew list to check the formulae of the installed mongodb

==> Formulae 
[email protected]   mongodb-dxxx... 

==> Casks
xxxxx
  1. In the terminal, type brew list [email protected] to get the directory of the mongodb installed in your machine.
/opt/homebrew/Cellar/[email protected]/4.4.13/bin/install_compass
/opt/homebrew/Cellar/[email protected]/4.4.13/bin/mongo
/opt/homebrew/Cellar/[email protected]/4.4.13/bin/mongod
/opt/homebrew/Cellar/[email protected]/4.4.13/bin/mongos
/opt/homebrew/Cellar/[email protected]/4.4.13/[email protected]
/opt/homebrew/Cellar/[email protected]/4.4.13/MPL-2
/opt/homebrew/Cellar/[email protected]/4.4.13/THIRD-PARTY-NOTICES

  1. Copy the bin path of your mongodb: /opt/homebrew/Cellar/[email protected]/4.4.13/bin

  2. Open up your .zshrc file with any text-editor

  3. Add this line to the file:

export PATH="/opt/homebrew/Cellar/[email protected]/4.4.13/bin:${PATH}"
  1. Try mongo --version in your terminal, if you see similar output like shown below, you are good to go.
MongoDB shell version v4.4.13
Build Info: {
    "version": "4.4.13",
    "gitVersion": "df25-----------b9246",
    "modules": [],
    "allocator": "system",
    "environment": {
        "distarch": "x86_64",
        "target_arch": "x86_64"
    }
}
