'Uncommon homebrew error: "Unknown command: switch"

I am in the process of trying to restart some legacy project that demands the use of an older version of openssl.

I have found good input on the issue here, which worked on one of my machines but not the other, which gives me the following error:

$  brew switch openssl 1.0.2t
Error: Unknown command: switch

The error does not seem to be very common, nothing helpful is showing up on a google/stackoverflow search.

What I have tried so far:

  • resolved all warnings shown by brew doctor
  • run brew update && brew upgrade
  • updated Xcode Command Line Tools
  • reinstalled openssl

What can I do to fix this?



Solution 1:[1]

I just used sudo:

sudo brew switch dart 2.16.0

and close the vs code and start again. That's it and run without any errors.
