I'm trying to run the rake secret command when I get this error:
rake aborted!
NameError: uninitialized constant Mysql2::Client::SECURE_CONNECTION

I've got the latest version of mysql and the gem mysql2. Has anyone else stumbled upon this issue recently? Most posts on this topic I've found here are some five years old and doesn't fix this problem.
Answering my own question here. This problem was caused by a mismatch between the mysql2 gem version (0.3.18) and the version specified in the gemfile (0.3.16).

I am trying to install an instance of Sharetribe on a heroku dyno. I am at the point where I am trying to create the database. I first tried rake db:migrate and it worked for most of the migrations but failed on one of them.
I was advised to use rake db:structure:load, so I tried that and I am getting an error from Heroku saying that mysql needs to be added to the PATH variable. Why is this, and how can I fix it? I'm not sure why it happens on db:schema:load and db:structure:load but not on db:migrate.
The complete stack trace with the error message is:
rake aborted!
failed to execute:
mysqlPlease check the output above for any errors and make sure that `mysql` is installed in your PATH and has proper permissions.

Thanks!
If you need to run heroku run bundle exec rake db:structure:load than you need to install mysql client.
To install additional packages you need to add Buildpacks (official or community based).
For mysql I successfully used https://github.com/din-co/heroku-buildpack-mysql
heroku buildpacks:add --index 1 https://github.com/din-co/heroku-buildpack-mysql
git commit --amend --allow-empty --no-edit
git push heroku -f
Heroku doesn't support mysql, you need to use pg gem in your gemfile in production block.
Please read Getting Started with Rails 5.x on Heroku

I'm a ruby on rails beginner, and I'm trying to run a rails app on my local mac. I have set up the environment and MySQL database, and it was all smoothie until the last setup step: db:migrate rake. I got the following error:
cannot load such file -- bundler/setup
/Users/snailwalker/vietnam/snailwalker/config/boot.rb:7:in `<top (required)>'
/Users/snailwalker/vietnam/snailwalker/config/application.rb:2:in `<top (required)>'
/Users/snailwalker/vietnam/snailwalker/Rakefile:5:in `<top (required)>'
What am I missing?
cannot load such file -- bundler/setup
Most probably the reason of this issue is that you don't have bundler. You should install bundler then try to run migrations again.
gem install bundler
bundle install
bundle exec rake db:migrate
Hope it'll help you.
I'm running Rails 4.0.3 on Ruby 2.0.0 on Windows 7, and have installed the DevKit (all x64).
I've installed the mysql2 gem using subst X: "C:\Program Files\MySQL\MySQL Server 5.6" and then gem install mysql2 --platform=ruby -- --with-mysql-dir=X:, and it installed fine. I then created a new app with rails new mysql_testy which ran fine, but when I run rails server I get the following error:

Do you guys have any idea what's happening?
Not sure if you figured it out yet, but I was having the same issue. I installed the 32 bit sql connector, copied the libmysql.dll file from it and pasted it into Ruby/bin folder. Opened a new command prompt and was able to connect to the server.
Before this step though you may have to reinstall a fresh MySQL2 gem pointing to the path of the connector: gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\mysql-connector\mysql-connector-c-6.1.5-win32\lib" --with-mysql-include="C:\mysql-connector\mysql-connector-c-6.1.5-win32\include" --with-mysql-dir="C:\mysql-connector"'
Hope this helps
I've been tinkering with this one for several days and I still get the same error. For starters, I have been able to start a newly rails app with sqlite as the database but the application we are working on uses Mysql. So when I go to the app directory and type "rails server" it gives me the following:

So (I think) MySQL development headers aren't installed, which I googled everywhere how to install them and tried most install command line to no success yet. Examples of commands I've tried:
gem install mysql2
sudo env ARCHFLAGS="-arch i386" gem install mysql -- --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib --with-mysql-include=/usr/local/mysql/include
I did the bundle install, bundle update and bundle commands in the app directory...I'm running out of options...can you help me?
I'm on mac osx 10.7
have you tried something like this, I'm one Mac OS X (lion) too and I have no problem with the mysql gem. Or may be you can find what you want here
[EDIT]
Or you can simply use ruby-mysql gem for development environment
