Installing SQLite3 on windows

I need to do some lightweight code testing so I decided to install
sqlite3 in my laptop (MS-WinXPproSP2) rather than have to create
PostgreSQl DBs. I installed the three required files (sqlite3.def,
sqlite3.exe, and sqlite3.dll) into the same directory as the ruby.exe,
which is on the path. I also installed the sqlite-ruby gem.

In my project root, when I type rake db:create I get this error thrown:

invert> rake db:create --trace
(in C:/Documents and Settings/byrnejb/My Documents/My
Projects/ca.harte-lyne.s
tem/invert)

Thank you! That was very helpful.

I got the same error as James and then I tried to run

gem uninstall sqlite-ruby

gem install sqlite3-ruby

as per your suggestions, but I get following error:

Please let me know what I can do ? I tried to copy sqlite3.dll file from
web and pasted in my config folder

Thanks in advance.

Probably not a good idea. Can you confirm that you have sqllite3 itself
installed ad working? And please post the output from ‘gem list’ and
‘gem environment’.

I did following and it worked:

  1. I downloaded sqlite3 dll zip from
    http://www.sqlite.org/sqlitedll-3_6_12.zip and unzipped into C:\ruby\bin
    and then ran
  2. gem install sqlite3-ruby -v 1.2.3

Thanks.
