My “sw_vers” shows the following info:
“ProductName: Mac OS X
But when I run “brew missing” or “brew doctor” I get the following messages:
“Error: unknown or unsupported macOS version: :mountain_lion”
“Please note that these warnings are just used to help the Homebrew maintainers with debugging if you file an issue. If everything you use Homebrew for is working fine: please don’t worry or file an issue; just ignore this. Thanks!
Warning: “config” scripts exist outside your system or Homebrew directories.
./configure scripts often look for *-config scripts to determine if software packages are installed, and which additional flags to use when compiling and linking.
Having additional scripts in your path can confuse software installed via Homebrew if the config script overrides a system or Homebrew-provided script of the same name. We found the following “config” scripts:
Error: unknown or unsupported macOS version: :mountain_lion”
What does this mean and what can I do to fix it?
As a side note, I’m wondering if it’s also the reason why I can’t install ImageMagick. I get the following error message for that even when I use --build-from-source … “Error: imagemagick: Unsupported special dependency :perl”
Thank you for any help!
