Upgrade to Yosemite deletes specific postgres directories and, as far as I can tell,
pg_config, so things like
psql are not availble.
install or verify dev tools (this is setoff an install script if dev tools not there)
# really verify dev tools is there
ls -la /Library/Developer/CommandLineTools/usr/bin
Re-create dirs deleted by Yosemite
mkdir /usr/local/var/postgres/pg_tblspc mkdir /usr/local/var/postgres/pg_twophase mkdir /usr/local/var/postgres/pg_stat_tmp
unlink postgresql, update, doctor brew,
brew unlink postgresql brew update brew upgrade postgresql
From install directions to link the plist for postgres init on boot
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
bundle (un)install pg and openssl
rvm get stable rvm list rvm uninstall <YOUR RUBIES> rvm install ruby #latest stable ruby version gem install pg #verify this will work
Now you can bundle in a project.
