(Crosses fingers, touches wood and searches for a black cat to cross his path.You don't seem to have postgres installed, check how to install postgresql in your system, one of the way isīrew install postgresql (if you use homebrew- recommended) I then did a brew unlink jpeg and brew link -overwrite jpeg.Įverything is working perfectly for now. The brew install -HEAD smpeg suddenly worked (although that might have been because I was no longer behind a proxy). I deleted everything brew doctor suggested and overwrote all links as suggested. I had some brew doctor issues (around 20!), which might have been due to me trying to install Pygame from source earlier and therefore manually installing all the dependencies, which then conflicted with homebrew. Pygame seems to be working without it though. Note: the smpeg install is failing for me at the moment, so I'll look into this a little more. If you have any problems yourself or a better way then please let me know in the comments. 2) Install Homebrew (ruby -e "$(curl -fsSL )")ĥ) brew install sdl sdl_image sdl_mixer sdl_ttf portmidiĩ) brew install python (needed to install mercurial)Īnd that's it.
