Answer 1

bundle update sqlite3
Have a look at this gist

Answer 2

Ah, looks like it’s an issue with the sqlite3 v1.4.0 gem which was released on February 4.
Mention the following sqlite3 version in your gem file:
gem "sqlite3", "~> 1.3.6”
Then make sure to “bundle install”.

Answer 3

You need the SQLite3 development headers for the gem’s native extension to compile against. You can install them by running (possibly with sudo):
apt-get install libsqlite3-dev
After which, be sure to run
bundle update sqlite3
