Talk personal, I’m not getting create a database for my Rails application it informs the following message :

Error

C: Ruby21-x64 Devkit Project>rake db:create DL is deprecated, Please use Fiddle rake aborted! Loaderror: Please install the mysql2 Adapter: gem install activerecord-mysql2-adapter (can’t Activate mysql2 (~> 0.3.10), already Activated mysql2-0.4.3-x64-mingw32. Make sure all dependencies are Added to Gemfile.)

Gem::Loadero: can’t Activate mysql2 (~> 0.3.10), already Activated mysql2-0.4.3-x64-mingw32. Make sure all dependencies are Added to Gemfile.

Tasks: TOP => db:create (See full trace by running task with --trace)

I don’t know why he started msql2 in version 0.3.10 and this causes the database not to be created. Any hints?

[UPDATE]

When I tell him to create the project he shows me this:

You’ve installed the Binary version of mysql2. It was built using Mysql Connector/C version 6.1.6. It’s Recommended to use the Exact same version to avoid potential issues.

At the time of building this Gem, the necessary DLL files Were retrieved from: http://cdn.mysql.com/Downloads/Connector-C/mysql-connector-c-6.1.6-win32.zip

This Gem includes vendor/libmysql.dll with redistribution notice in vendor/README.

  • It seems that the mysql adapter for ruby is not installed, use the command gem install activerecord-mysql2-adapter to install the adapitador and use gem update --system to update mysql2, your version is 0.3.10 and Rails is requiring version '0.4.3`

  • I already try to install actierecord-mysql2-Adapter but he says he installed but when I give the db:create rake again he asks again

  • When I speak to him he creates the project he shows me this: You’ve installed the Binary version of mysql2. It was built using Mysql Connector/C version 6.1.6. It’s Recommended to use the Exact same version to avoid potential issues.

The problem is not in ruby, it is not finding is windows Dlls to connect with mysql.

Download the file that talks about the error: 

http://cdn.mysql.com/Downloads/Connector-C/mysql-connector-c-6.1.6-win32.zip

Then extract in C: mysql-Connector folder

Then turn on the terminal:

gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:\mysql-connector"'

And see if it installs.

  • I already did that and still it continues with the same error, as I said after the installation it sends an update error message that is here.
