Run a rails project on a new mac for the first time

Make sure that Rails project's ruby version has been installed on this machine. You might need to install an older version of Ruby, by entering this in Terminal:

rvm install x.x.x

Clone a project from GitHub

Go to that project, then get the github url. Then CD to the directory where it should live, like:

cd ~/code/active

Then clone the repok for example:

git clone https://github.com/CasJam/zipmessage.git

Install all of the project's gems by running:

bundle

Then create the database:

rails db:create

Then migrate the database:

rails db:migrate

You might need to run these as well:

yarn

And then:

rails assets:precompile

Now you should be able to run the server:

rails s

Then view the app at either of these:

http://127.0.0.1:3000/

http://localhost:3000/
