Failing to install activerecord-jdbcmysql-adapter gem
- by Phil Sturgeon
I am trying to follow the basic "Create a blog in 20 minutes" Rails screencast but have hit a stumbling block already.
When I try to rake db:migrate I get errors about the gem activerecord-jdbcmysql-adapter not being installed. When I try to install it, I am told it doesn't exist.
If I try to simply gem install mysql I get all sorts of madness appearing.
I am running this on Mac OS X 10.6.2 and my installation was all done through gem. My basic setup works (Hello world!).
Here is the error log:
$ rake db:migrate (in /Users/xxxx/Sites/blog) rake aborted!
Please install the jdbcmysql adapter:
gem install activerecord-jdbcmysql-adapter (no such file to load -- active_record/connection_adapters/jdbcmysql_adapter)
(See full trace by running task with --trace)
