title: Rails Locally Installing Rails Application rake db:migrate returns
body: <p>I have a private Rails app that I'm trying to install locally. It's currently running in a hosting environment but I'd like to install it locally to begin making changes. I've already worked out that I can make deploy updates to the 'live' server but a recent misstep 'reinforced the need to make changes locally'. </p>
  
  <p>After a fair amount of reading I determined that I needed to...</p>
  
  <ol>
  <li>Grab the latest repository (It uses SVN)</li>
  <li>Grab the database mysqldump -u root --databases my_db_development > my_db_development_0110.sql</li>
  <li>Imported database locally (MAMP/Sequel Pro noticed there was no data in the database although there is data in the live server <strong><em>- is that strange?</em></strong>)</li>
  <li>Validate database.yml (adapter: mysql, encoding: utf8, database: my_db_development, username: root, password: , host: localhost)</li>
  </ol>
  
  <p>The next step I assumed was to get into my local directory and <strong><em>rake db:migrate --trace</em></strong> which returned the output below. </p>
  
  <p>I'm a bit unsure how to go about understanding and identifying why I'm unable to move forward. Any ideas as to whether I've missed something or perhaps need to change something?</p>
