After an OS upgrade you may find several gems broken, usually gems that rely OS dependent components(libraries, etc..)
If you’re using rvm/gemsets and bundler it’s pretty simple to reinstall all gems with their native extensions:
rvm gemset empty gemset-name
bundle install
If bundle install does not work – you may need to install bundler first:
gem i bundler
have a rails app and need sqlite3 gem compiled on your freebsd environment?
gem install sqlite3 -- --with-sqlite3-include=/usr/local/include --with-sqlite3-lib=/usr/local/lib
and if you need to use bundler for a rails 3 app, you should do
bundle config build.sqlite3 --with-sqlite3-include=/usr/local/include --with-sqlite3-lib=/usr/local/lib
bundle install
rake db:migraine 🙂
