【问题讨论】：

cannot load such file -- sqlite3/sqlite3_native (LoadError) on ruby on rails的可能重复

标签： ruby-on-rails

【解决方案1】：

确保您的 gem 已正确安装并使用正确版本的 sqlite。检查你的 Gemfile 中有这个：

gem 'sqlite3',  '~> 1.3.11'

然后从项目的根目录运行

bundle install

如果您还没有运行，您可能还需要运行它。

rails db:create db:migrate #this is for rails >= 5

或

rake db:create db:migrate  #rails <= 4.2
