Problem installing mysql gem

rubyonrails-talk
1

Hi guys,

I'm totally new in ruby. I'd appreciate some help.

I followed the Getting Started guide in www.rubyonrails.org, and got the server up and running on a sample app I've created, as the guide perscribed.

Now I'm stuck with the installation of mysql gem.

I've tried "gem install mysql -- --with-mysql-config="c:\Program Files \MySQL\MySQL Server 5.0\scripts\mysql_config". All I got was:

Successfully installed mysql-2.7.3-x86-mswin32 1 gem installed Installing ri documentation for mysql-2.7.3-x86-mswin32... Installing RDoc documentation for mysql-2.7.3-x86-mswin32... ERROR: While generating documentation for mysql-2.7.3-x86-mswin32 ... MESSAGE: Unhandled special: Special: type=17, text="<!-- $Id: README.html,v 1.20 2006-12-20 05:31:52 tommy Exp $ - ->" ...

I've downloading the api by my self and install it, but it keeps failing on:

Did you try

gem install mysql -- --with-mysql-config="c:\Program Files\MySQL\MySQL Server 5.0\scripts\mysql_config" --no-rdoc --no-ri

Looks like its the doc generation thats failing...

I'm also having the same problem. Tried that ant it still doesn't work.

In addition, I'm getting this when trying to run in rails:

The specified module could not be found. - c:/ruby/lib/ruby/gems/1.8/gems/mysql-2.7.3-x86-mswin32/ext/mysql.so

Try installing MySQL in a directory without any spaces, e.g., c: \mysql5. And then try installing the mysql gem. Bharat

Ok... found the solution. At least for me.

remove the RUBY_HOME\lib\ruby\gems\1.8\gems\mysql-2.7.3-x86-mswin32\ext\mysql.so and everything will work again.

Also, some people noticed that this files is also on RUBY_HOME\lib\ruby\site_ruby\1.8\i386-msvcrt

Removing or renaming this file fix the problem as suggested on this thread http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/55dd057c41a72fc5

Thanks anyway. =)
