When I try to run Rake (also with Rails commands) commands I got this error :
Rake aborted! cannot load such file -- arel/visitor/mysql
/config/application.rb:7:in <top (required)>
/Rakefile:4:in 'require_relative'
MySql database works perfectly, and I've added gem 'mysql2' in Gemfile.
Using --trace argument :
rake aborted!

Rake --version: 13.0.1
I think you should remove arel:
gem uninstall arel
After that run:
bundle install
This should fix problem.
I also faced with this and agree with Nezir.
I believe that in my case, this happened because of such actions:
MySQL 5.7.30 -> MySQL 8.0.20 -> MySQL 5.7.30
The first time I had MySQL 5.7.30 it was fine with
bundle exec rake db:create db:structure:load
I faced this error while working with a legacy application, and here is the solution which worked for me. Hope this will work for you.
https://gist.github.com/SahSantoshh/fffbfbaa91f82b46ef8aa39922ee889e
Uninstall ruby
reinstall ruby
if db is running then It's fine if not, then run MySQL 5.7 using docker https://gist.github.com/SahSantoshh/8ff41ce4dd57305358e98d43adff76b1
hit bundle
run rake db:migrate
I'm trying to run a locally Jekyll server to check my side but after the run: jekyll serve command, I get:

Check first if you can install libyaml:
on MacOS
or on Linux
Then gem install psych
Check out also rbenv/ruby-build issue 1251 and the GEM_HOME setting.

Thanks in Advance
Resolved by adding a Gemfile.local inside redmine directory
# Gemfile.local
gem 'multi_json'
gem 'json'
then run bundle lock --add-platform x86_64-linux (get your platform from ruby -v)
followed by bundle install --without development test
I'm just starting out with Rails and am following the Ruby on Rails essential training course and get problems trying to start WEBrick. Assuming it has something to do with my installation of mysql but not sure.
I made sure that I am in the correct directory (:C\sites\simple_cms)
I ran 'bundle install' before running 'rails s'
I followed these guides to get the gem installed (second to last entry): https://github.com/brianmario/mysql2/issues/372
I have ruby 2.2.1p85, rails 4.2.1 and this rubygem: mysql2-0.3.18-x64-mingw32 installed
Would appreciate some help from y'all :)
