$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc

$ echo 'eval "$(rbenv init -)"' >> ~/.bashrc

$ exec $SHELL

$ git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build

$ rbenv install 2.7.2

$ rbenv global 2.7.2

$ ruby -v

# Arch users can skip first command
$ sudo apt-get install -y libreadline-dev zlib1g-dev

$ gem install bundler

$ gem install rails

$ rbenv rehash

$ rails -v

Install MySQL

Ubuntu

$ sudo apt install mysql-server

$ sudo /etc/init.d/mysql start
# check this issue if it gives error
# https://github.com/wslutilities/wslu/issues/101

$ sudo mysql_secure_installation

Arch

$ sudo pacman -S mariadb

$ sudo /etc/init.d/mysql start
# If you get an error run next 2 commands otherwise skip

$ sudo mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

$ sudo systemctl start mysqld

$ sudo mysql_secure_installation

ALWAYS use a password containing uppercase, lowercase, and special characters or else MySQL will give error (eg. Test@1234)

Common Errors

If you get a MySQL error during bundle install
