I can't run “bundle update” because of “mysql2” gem

Question

I have this in the Gemfile:

gem \'mysql2\'

But when I run bundle update, I get this error message:

An error oc         


        

Answer 1

Looks like there is no mysql2 gem installed in your machine.As you are using Mac OSX,you should be installing mysql2 gem like this

gem install mysql2 -- --with-mysql-dir=/usr/local/opt/mysql/ 

If the above command did't work,try like this

sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

And after try

bundle install

This should fix the error.
