How I installed MySQL, RVM, Ruby, and Rails on Lion
Install MySQL on Lion (Mac OS X 10.7)
Download the 64-bit .dmg of MySQL and install everything it comes with.
Add the following lines to your ~/.profile file
export CC=/usr/bin/gcc-4.2
export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH"
Go to the MySQL panel in System Preferences and start your MySQL Server
Then run these commands in terminal:
cd /usr/local/mysql
sudo ./scripts/mysql_install_db
sudo ./bin/mysql_secure_installation
Install RVM, Ruby, and Rails on Lion
Open up terminal and run this command:
bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
Add the following line to the end of your ~/.profile file
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function
Restart terminal, then run the commands:
rvm install 1.9.2
rvm use 1.9.2
rvm gemset create rails3
rvm use 1.9.2@rails3 --default
You can now gem install rails, gem install rails -v=3.0.4, bundle install, etc.
