I need to delete all mongoDB thing in my mac.

i followed the uninstall guide on mongoDB uninstall official guide

but on step 2 which is

`launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist
rm -f ~/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist
launchctl remove homebrew.mxcl.mongodb-community`

i got this error:
