ERROR: While generating documentation for mysql

Error while running the command
gem install mysql
in windows xp

Produced this error:

C:\>gem install mysql

ERROR: While generating documentation for mysql-2.7.3-x86-mswin32

(continuing with the rest of the installation)

Solution:
set path=%path%;c:\mysql-5.1.33-win32\bin\

I then copied the libmysql.dll from the above bin into the ruby bin (I'm not sure this is necessary, but it was one of the steps). Note copying the libmysql.dll from the mysql tools did not work, it has to be from the mysql server files. An easy way without installing mysql server is to use the mysql noinstall zip.

I then ran the command
gem install mysql --no-rdoc

I still get an error if I run gem install mysql, but with the no-rdoc the ruby server is able to run.

You can now delete mysql-noinstall and your site should work.
