teratailを初めて使ったので、質問の仕方に失礼がありましたら申し訳ございません。

試したこと

Puma caught this error: Error loading the 'sqlite3' Active Record adapter. Missing a gem it depends on? can't activate sqlite3 (~> 1.3.6), already activated sqlite3-1.4.0. Make sure all dependencies are added to Gemfile. (LoadError)

とかいてあったので、
$gem 'sqlite3', '> 1.3.6'
を打ってみたが、
gem 'sqlite3', '
> 1.3.6'
ERROR: While executing gem ... (Gem::CommandLineError)
Unknown command sqlite3,
こう出てしまい、ダメだった

gem 'sqlite3', '~> 1.3.6' は、コマンドラインで実行するのではなく、Gemfile内に記載するものです。
その後、bundle installでインストールします。
