I am relatively new to using the terminal, ruby on rails and ruby gems and have been scratching my head (ie searching google) for a few hours now, any help would be greatly appreciated. Have tried the sudo command but no luck there.

Answer 1

You should install sqlite3 in your OSX first

brew install sqlite3

Answer 2

Ok, so I ended up throwing the kitchen sink at this one in the end. Here are the steps I took to resolve the issue.

1. uninstalled RVM link
2. uninstalled App Store version of xcode as had it previously installed link
3. ran $ xcode-select --install in terminal to install command line tools

4. as I already have Homebrew installed I added Homebrews binary path to the front of the $PATH link

   $ echo 'export PATH=/usr/local/bin:$PATH' >> ~/.bash_profile $ source ~/.bash_profile

5. ran $ brew install sqlite3 command
6. reinstalled RVM

I believe the steps which mitigated the issue the most were 2,3,4 and 5.

Hope this helps!
