为什么不安装捆绑软件安装程序？

因此，诚然，这部分是我的错。这一切都是因为我想安装引导程序而开始的。我掉进了一个兔子洞，因为它最初没有用，所以现在我的控制台中不断出现这些错误。

我现在想做的就是运行“捆绑安装”。大约十五分钟前，它运行良好，现在我收到以下消息：

    current directory: /home/ubuntu/.rvm/gems/ruby-2.6.3/gems/pg-1.1.4/ext
/home/ubuntu/.rvm/rubies/ruby-2.6.3/bin/ruby -I /home/ubuntu/.rvm/rubies/ruby-2.6.3/lib/ruby/2.6.0 -r ./siteconf20200613-11040-1x5o4mg.rb extconf.rb
checking for pg_config... no
No pg_config... trying anyway. If building fails, please try again with
 --with-pg-config=/path/to/pg_config
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
*** 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:
        --with-opt-dir
        --without-opt-dir
        --with-opt-include
        --without-opt-include=${opt-dir}/include
        --with-opt-lib
        --without-opt-lib=${opt-dir}/lib
        --with-make-prog
        --without-make-prog

        --curdir
        --ruby=/home/ubuntu/.rvm/rubies/ruby-2.6.3/bin/$(RUBY_BASE_NAME)
        --with-pg
        --without-pg

        --without-pg-include=${pg-dir}/include
        --with-pg-lib
        --without-pg-lib=${pg-dir}/lib

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

  /home/ubuntu/.rvm/gems/ruby-2.6.3/extensions/x86_64-linux/2.6.0/pg-1.1.4/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /home/ubuntu/.rvm/gems/ruby-2.6.3/gems/pg-1.1.4 for inspection.
Results logged to /home/ubuntu/.rvm/gems/ruby-2.6.3/extensions/x86_64-linux/2.6.0/pg-1.1.4/gem_make.out

An error occurred while installing pg (1.1.4), and Bundler cannot continue.
Make sure that `gem install pg -v '1.1.4' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  pg

所以然后我检查该文件，错误将我定向到（mkmf.log），并且收到以下消息：

请帮助，我正要拔头发。这非常令人沮丧。
