railsアプリの開発準備をしています。
データベースをSQLiteではなくpostgresqlにしてアプリを新規作成したいと思っています。
Postgresqlを含め、ある程度基本的なインストールを済ませることができましたが、
scaffoldをgemに追加してbundleinstallすると以下のようなエラーが表示されます。
エラーの原因をお教えいただけますと幸いです。

エラーメッセージ

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

  /home/vagrant/.rbenv/versions/2.5.7/lib/ruby/gems/2.5.0/extensions/x86_64-linux/2.5.0/pg-1.2.2/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /home/vagrant/.rbenv/versions/2.5.7/lib/ruby/gems/2.5.0/gems/pg-1.2.2 for inspection.

An error occurred while installing pg (1.2.2), and Bundler cannot continue.
Make sure that `gem install pg -v '1.2.2' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:

mkmf.logを開きましたが、以下のような構文が連なっていました。

試したこと

エラー文中にある

gem install pg -v '1.2.2'

を実行してみましたが、行頭が「>」となり、インストールなどの動きはありませんでした。
