I've been struggling with this problem for a few hours and it is preventing me from even starting my server, which therefore is stopping development completely.
I am running Windows, Bitnami Rubystack, and that's pretty much it. I downloaded and installed NetBeans yesterday but my primary editor is Notepad++. I am not using JRuby.
Here is the exact message (upon trying to start ruby script/server):
irb: gem install activerecord-jdbcmysql-adapter
ERROR: Could not find a valid gem 'activerecord-jdbcmysql-adapter' (>= 0), here is why:
Found activerecord-jdbcmysql-adapter (0.9.7), but was for platform java
I have tried the following commands:
gem install activerecord-jdbcmysql-adapter
gem install activerecord-jdbc-mysql-adapter
gem install --platform java activerecord-jdbcmysql-adapter (installed but didn't help, uninstalled again)
gem install rails (now 2.3.8)
gem update --system (now 1.3.7)
Any help would be much appreciated. Thanks.
