bundle install で エラーが起きたとき…

More than 3 years have passed since last update.

bundle install

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle
as root will break this application for all non-root users on this machine.

An error occurred while installing sqlite3 (1.3.9), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.9'` succeeds before bundling.

cd /usr/bin 

ls | grep sqlite
sqlite3

sqlite3がインストールしてあるのにgemでsqliteがインストールするさいにエラーが起きるのはなぜだろうと調べたらどうやら

sqlite-devel

をインストールしていないらしいことがわかったので

yum install sqlite-devel

をインストールしたら

gem install sqlite3

をインストールできました。

gemでのインストール関連はどうやら結構エラーが起きることが多いみたい。
