Unable to Install Redmine on Win 2008R2 .. gem install activerecord-mysql-adapter not working

Question

While trying to install Redmine on Windows Server 2008 R2, I struck into following error we no solutions found...

It is asking to install something, and when try to install it says it don't find it. It suggested activerecord-mysql2-adapter, but even that is not working...

I'm now starting to believe that ROR sucks....

C:\Ruby\Apps\Redmine>rake db:migrate
rake aborted!
Please install the mysql adapter: `gem install activerecord-mysql-adapter` (193:

Answer 1

根据您的database.yml adapter行，尝试使用gem install mysql或gem install mysql2 。

Answer 2

possibly error in your database connection, verify your mysql is running and if running verify your sql connection setting in database.yml

I too faced this problem, but changing database.yml connection worked for me
