Ruby 2.5.7 Rails 5.2.4
This is an article for my memo, but I couldn't find an article explaining this error. I hope it will be helpful to anyone.
For learning, I tried to change the template engine of the Rails application I'm currently writing from erb to slim. It was going to be a heavy refurbishment, so leave the existing application as it is, make a copy and slim it.

Copying of GitHub repository and application is completed, and when I try bundle install in the copied app directory for slim, the following error occurs. (At this point, there is no error in the copy source application.)
$ bundle install
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

An error occurred while installing mysql2 (0.5.3), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.3' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
mysql2
mysql client is missing. You may need to 'sudo apt-get install libmariadb-dev', 'sudo apt-get install libmysqlclient-dev' or 'sudo yum install mysql-devel', and try again.
I'm asked to try this sentence of error and 3 patterns of commands, so I'll try them in order.
$ sudo apt-get install libmariadb-dev
sudo: apt-get: command not found
ʻI was told that the apt-getcommand could not be found, so skip the second'sudo apt-get install libmysqlclient-dev' and try the third'sudo yum install mysql-devel'` ..
$ sudo yum install mysql-devel

Complete!
You will be asked if you want to download the package on the way, so enter y and press Enter.
The mysql-devel entered in the command is the package management system required to run mysql on the server, and this time the missing mariadb-devel is downloaded.
Download completed normally, again
$bundle install
When you do, it completes normally.
I could understand the package management system, but I couldn't understand how mariadb-devel was involved in this error, so I would appreciate it if you could let me know in the comments.
Also, if you have any questions, differences in interpretation, or if you feel something is wrong with the description method, we would appreciate it if you could point it out in the comments.
Thank you for reading until the end.
