The two pics above are brew config and brew doctor. And I tried to brew install luajit-openresty, It doesn't work

Please don't send this kind of information as images, it's the absolute worst way to relay a text based output.

You're working with a very old Homebrew version (9 months). Do brew update, and if that doesn't work run brew update-reset to update it before trying again.

Ok, thx. I'll try and show my terminal display in a better way
