sqlite3.h is missing. Try 'brew install sqlite3',
'yum install sqlite-devel' or 'apt-get install libsqlite3-dev'
and check your shared library search path (the
location where your sqlite3 shared library is located).
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /home/user/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/extensions/x86_64-linux/2.5.0-static/sqlite3-1.4.1/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /home/user/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/gems/sqlite3-1.4.1 for inspection.

エラー内容を見てみて下記の文言があったので

sqlite3.h is missing. Try 'brew install sqlite3',
'yum install sqlite-devel' or 'apt-get install libsqlite3-dev'

下記のコマンドを実行。

sudo apt install git sqlite3

それでも解決しない状況です。（エラーの内容に変わりはないです。

Answer 1

sudo apt install libsqlite3-dev は実行しました？（エラーメッセージに書いてあるコマンドをアレンジ）

sudo apt install libsqlite3-dev

を実行した後に

gem install mailcatcher

で無事にインストールすることが出来ました！
